While some self-proclaimed custom builders simply buy a frame and an S&S engine, pick out some slick controls and trick wheels, then bolt it all together and call it a one-off motorcycle, on that rare occasion you run into a craftsman who still takes the time to do things the old-fashioned way, pounding sheet metal meticulously by hand, bending tubing by blowtorch and elbow grease. Wayne Ransom is a young custom builder in this vein.
Ransom Motorcycles first caught our attention a couple of years back by sourcing sportbike engines for its customs instead of the traditional V-Twin. The prior builds were heavier on bodywork, showcasing Ransom’s sheet metal skills, so when we got our first peek at the aggressive, streamlined-design of his latest build, The Serpent, we liked this new direction.
Ransom's latest creation takes its lines and hones them to a razor-sharp edge in the exotic motorcycle called The Serpent.
The bike is full of points and angles, from the spear-like end caps on the 56mm Mean Street fork to the blades of the black RMD Billet Predator Wheels. The tank’s lines roll down the back before coming to a point at the small, sheet metal tail. The aluminum radiator shrouds on both sides of the bike look like they’d cut your finger if you ran it down their edge. Even the shields at the end of the stainless steel exhausts are aggressively angled. The Serpent looks more like a Euro-style streetfighter than the creation of a small custom house out of Jersey.
Look for welds connecting the tank, seat, and tail and you won’t find them. The artistry of the bike’s topside might be Ransom’s crowning achievement in fabrication. The fuel tank, seat, tail, taillight, battery box and instrument panel are contained in one aluminum piece. They integrate so seamlessly that, as Ransom put it, “looks like it’s poured from a mold.”
The sides of the tank rise up to form two scalloped ridges. In between the ridges, a digital speedo and an analog tach from a GSX-R are integrated into the top of the tank. The tank’s fluid design flows cleanly into the small triangular patch of a seat by Kustom Seat Kreations, and with no rear fender, Ransom incorporated the taillights under the seat. The amazing part is, when it comes time to service the engine, just loosen five bolts and the whole top comes off.
All of this sits perfectly on the backbone of a silver tubular trellis frame. To give the bike the same aggressive attitude inside as out, Ransom sourced the formidable powerplant from a 2008 GSX-R1000. Just as in Eve, the frame sits below the tubular frame and serves as a stressed member. Ransom generally decides on what engine to run before building so when it comes time to mount the mill it’s a bolt-on job for the most part. He also used the stock Gixxer Thou transmission, but the 4-into-1 exhausts running below the bike are his design.
The combination of no fender on the backside along with a single-sided swingarm put the full focus on the black mass of the 300mm Avon Venom tire (The Serpent, Venom, Predators – I sense a theme here). The thick swingarm he made is attached to dual Works Performance Shocks, a feature the owner appreciated as he went out on his 150-mile weekend ride a few weeks back.
The bike is long and low, with a 69-inch wheelbase and a fork set out at a 39-degree angle. The 21-inch tall front tire helps maintain the bike’s aesthetic balance between its beefy backside. The rider’s triangle is sport-oriented with the black Ransom-made handlebars set low, the Vortex foot controls rearset and a moderate seat height .
Small features like silicone brake lines and a compact, powerful Eurocomponents headlight complement the tidy build. Ransom sought the services of Xtreme Kreations’ Jim Caruso to apply the wicked paint and pinstriping that breathe life into the bike. Ransom’s signature Cross logo, a testament to the One who inspires his work, is painted in the middle of the side-mounted license plate holder and on top of the headlight. No weight is listed, but Wayne has a habit of keeping his builds on the lower end of the scale by using aircraft-grade aluminum and Titanium. With a low curb weight (for a custom), a screaming literbike engine, and a chassis capable of keeping that power planted, Ransom wants his customs to be ridden hard, stating “I don’t like to compromise performance for looks.”
It’s a treat in this business to witness a custom builder’s skills evolve. With many talented builders out there, But Ransom has come a long way since we first met. His fabrication skills warrant attention, and something tells me we’ll be seeing him again somewhere along this long and dusty road.

The Rocker or the Rocker C is the Custom Chopper created for the person that has cast a glancing view to the custom or chopper motorcycles that have populated the scene a few years back. The problem with some of the past customs or choppers was the price and reliability. Some of the custom designed parts, chopped frames and extended forks gave the creations a terrific profile, but, often times created riding and dependability problems. This is not to say that all customs and choppers had a problem, but there were some with problems and of course resale was always a concern for these special creations.
Now Harley has a factory custom chopper that has a lot of the upgrades without the extremes often associated with some of the creations of the past. Plus, it was engineered and designed for reliability and ride ability that very few people can create without the deep pockets of someone like Harley-Davidson. Now, with the Rocker, you can have your chopper profile, dependability and service ability with a huge selection of off the shelf performance and chrome upgrades.
What makes this a Harley is the Softail frame with a rigid mounted Electronic Sequential Port Fuel Injection 96B twin Cam, 6 Speed power plant. And of course all of the hand controls are the same throughout the line as for brake pedals and hand controls. It has a speedometer, no tach, with the turn signal and neutral indicators in a little display on the fuel tank.
What sets this beast apart from the standard line is the extended front forks and large 240 mm rear tire. The wheelbase of this custom is only about 5 inches longer (69.2 inches) than the standard Softail. Besides the chopper profile, they enhanced the custom look with a rear fender that hugs the oversized rear tire with custom wheels by mounting it to the swing arm and finished it with a nice color keyed frame.
On the Rocker C, if you haven’t noticed, they have what appears to be a solo design. But, should you get lucky, there is a passenger seat that is conveniently hidden under the solo seat. It appears to be a little torture pad. But should you need it, it could be your friend. Just a quick note about the seat; I rode the Rocker with it hidden under the seat and with it in place. Now for vanity reasons, you would want the hard solo look for bar hopping, but should you venture out on the road, with the seat in place, it actually gives a little lower back support for more comfort.
As you can see in the picture there is a stage one upgrade. This included new exhaust pipes and dyno tuned remapping. I recommend this upgrade for all Harleys, with the exception of the V-rod, for performance reasons. Pictured are the Vance and Hines Big Radius 2 into 2 Black pipes that sell for $799.22. This is a great upgrade.
I have ridden choppers in the past and never really like the ride. It was a full time job to manage that 300 rear tire over uneven pavement and speed bumps and the turning radius was poor when you turn around or when maneuvering around in a parking lot. Climbing on the Rocker the first thing that I noticed was the nice low seat. Your feet are flat on the ground and with your legs bent, you have the feeling that you are wearing the bike rather than just sitting in it. After grabbing the slightly curved back handlebars on risers, I noticed that they had internal wiring. That gave it a very nice clean look. But not to be distracted with the great look of this new toy, I wanted to find out if this machine really rides like any of the Harley’s that I have ever been on.
Surprisingly, after getting out of the parking lot, I noticed very little difference from most of the softails that I have been on in the past. The upgraded Vance and Hines pipes sounded great and low end torque increase from the stock Softail was noticeable. The steering was light and easy. It was nothing like some of the choppers from the past.
The Twin Cam B power plant is very smooth, even with setting at idle stopped. After negotiating some nice long curves on the back roads, you notice that you lean a little more then on some of the shorter wheel base machines. Then with a slight twist of the grip, the extra low-end torque really felt good powering out of corners. This is a very easy to ride custom. Just to see if there were any problems with turning, I slowed to a crawl and made a u-turn on a two lane, it was a piece of cake.
After finding an on-ramp to the local freeway, I was able to find the throttle limit and was pleasantly surprised at the power. Straight as a rocket, you could easily find a three digit number by the time you have to merge with traffic. Then of course, you have to grab a little brake to blend into with all of the cages. On the freeway, it rides like a dream. With the sixth gear, you can idle down the road with ease and you always have plenty of power.
I rode this Rocker on curvy roads to interstate riding and, at all times, found that this little Rocker was a champ and a pleasure to ride. It is obviously not a cruiser, nor is it a Buell, but you could spend the day on the bike and feel great at days end. What really sets this ride apart is the styling. Even with the exotic styling, for a Harley, it is a very tame ride when compared to the old style hardtail choppers. It is a ride that you want to be seen on.

The radial engine is a thing of beauty and it looks like several other folks think the same thing. After I posted the radial motorcycle yesterday, I contacted Rotec Engineering, makers of these 7 cylinder radial engines, and according to them, there are at least 4 of these projects in various stages of completion at the present time. Yesterday's bike and this one as well seem to be a bit short of running. I see no provisions for exhaust yet and no front brakes. This bike has no handlebars either so we're still in the building stage. At first glance, you wonder if these guys are serious but these do seem to be real works in progress.
Additional closeup photos on yesterday's post show exhaust pipes behind the engine and at least a foot brake pedal so it may be running as is.
This longitudinal engine arrangement seems more natural for a motorcycle, better clearance for cornering, however, cooling the rear cylinders would definitely be a problem. Yesterday's transverse arrangement is great for cooling and correct for the engine's design but it presents clearance problems, not only straight up for the bottom cylinder but when leaned in either direction, as well.
I can't believe these bikes will be much more than showpieces when done, who could actually ride them? Still, I think radial engines are among the best looking engines ever designed and these Rotecs are small enough to put in all sorts of different things, airplanes look great with a big radial out front but there are always cars, trucks, boats, you name it. But you have to give these guys credit, a radial engined motorcycle, superb!

Triumph Bonneville SE and Ducati GT 1000 touring.
The Bonneville moniker first affixed itself to Triumph’s 650cc Parallel Twin-powered T120 in 1959, a high-performance ride through the ‘60s that earned its classy moniker as a tribute to the land speed racing exploits of the British marque during the 1950s. A second Bonneville incarnation, dubbed the T140, upped displacement to 750cc but ended production with Triumph’s decline and near obliteration in the early ‘80s. The Bloor restoration of the historic English marque saw the Bonneville’s return in 2001, where it has since anchored the company’s Modern Classics.
Triumph expanded the Bonneville line by two additional models, with an all-new base model and SE version. The two join the long-standing Bonneville T100, which continues in the Modern Classic line, relegating its spot as the flagship to the new Bonneville. The new Bonnie varies from its T100 with smaller ergos and wheels, the hoops being two inches smaller and cast instead of wire-spoked. As for the difference between the base Bonneville and the SE, it’s cosmetic, with the SE sporting a tank badge, aluminum engine cases and a two-tone paint scheme with pinstripe, as well as the inclusion of a useful tachometer on the instrument console. All three Bonnevilles, as well as the entire 2009 Modern Classic Twins, are fuel injected for the first time to meet US emissions.
Right out of the box, the Bonneville struck an authentic chord in the looks department. The Bonneville SE we tested generated, by far, the most awestruck praise from roadside gawkers – quite a compliment considering Ducati’s undoubted skill at producing sexy bikes. And this was in spite of the SE’s lack of wire-spoked wheels, which is such a huge part of the vintage look. Were I to purchase a Bonneville, I’d have to tap the wire-spoked T100 for this very reason alone. The Trumpet scores a big win over the Duc in the very subjective styling comparison.
As for the motor, the Triumph’s 865cc Parallel Twin doesn’t measure up to the Ducati, down 127cc to it competitor. Engine performance expectations have dramatically inflated since the Bonnie’s debut 50 years ago. The modern Twin cranks 58 horsepower at the rear wheel and 44 lb-ft torque. It doesn’t take long at the controls to realize the Bonneville motor is tuned for a more leisurely riding approach - much different than the Ducati’s rip-snorting L-Twin.
Yet the Triumph Twin delivers enough pep to motor up to triple digits and is spunky in its 4000 rpm sweet spot. The old riding bromide about riding a slow bike fast rings true on the Bonneville – a rider with moderate skills will be pushing the Twin to its limit. There’s a certain thrill in that
Seamless power delivery and user-friendly throttle feel highlight the Twin’s traits. Considering it’s the first year of fuel-injection for the Modern Classics, Triumph nailed it first time around. The two-stage choke, unlike the carbs, is real and needed on cold starts. As for those faƧade carbs, explaining them to curious onlookers is an amusing novelty at parking lots and gas stations – particularly to riders who claimed they could tell the Bonnie was carbureted by its sound or smell…
Smooth and easy, a rider can’t get lost in the Triumph’s 5-speed gearbox. Teamed with one of the lightest clutch lever pulls we’ve sampled, the transmission lends itself well to entry-level riders who won’t be missing shifts or fumbling with neutral at stop lights.
One disc down up front compared to the dual-disc Ducati, the Triumph brakes without drama via a single 310mm rotor up front. Head to head, the Duc’s dual Brembo calipers deliver superior feel, but Triumph’s Nissin 2-piston caliper binders make confident, controlled stops. While the lever is stiffer on the Triumph, there weren’t any helter skelter moments for us under hard braking.
After the motor, handling performance is where the Triumph loses the most ground on the Ducati. Its softer 41mm Kayaba fork hinders high-speed maneuvering, and while the dual rear shocks (also Kayaba) are pre-load adjustable, railing in tight terrain overtaxes both the suspension units. That said, the Bonneville handles sharp at lower speeds with its low center of gravity, and is one of the easiest-to-ride shifting motorbikes we’ve ever sampled.
The Bonneville ergonomics fit smaller-statured riders well, Triumph lowering the seat height to 29.5 inches and repositioning the bars down and toward the rider. While it didn’t gel as well with my 6’1” frame (probably anyone approaching 5’10” will be too big) the riding position is upright, standard and comfortable, except for one big, huge, gigantic, stupendous caveat (brace yourself, a seat diatribe on its way…).
Short distance jaunts on the Bonnie are fine, but we started getting uncomfortable after about 100 miles, perturbed at 150, and delirious about the 200-mile mark in the Triumph’s excruciating saddle. The new Bonneville’s seat height is lower, in part, because they sculpted some foam out. Bad idea! I wondered how the SE’s seat would hold up on long distance rides during our brief sub-100-mile test ride at the official press launch in New Orleans. Now I know, and my tookus still whines, “remember that day you rode 250 miles on the Bonneville SE? Man, I will never forgive your ass for that!”
Admitting that… The two-inch lower seat height, along with a narrower tank, makes the Bonneville feel way smaller than the Ducati, even though at 497 lbs (472 lbs tank empty) it is actually a full 31 lbs heavier. The small dimensions make mincemeat out of those tricky low-speed maneuvers that really jump out and bite beginners.
The Bonneville and GT recorded almost identical fuel efficiency – the Triumph edging out a 48.6 to 47.3 mpg advantage. The Bonneville has a slightly bigger fuel tank too, 4.2 gal to 3.9 gal, with a theoretical range near 200 miles. The strange thing is the Bonneville always seemed to want gas first during our 750-mile test ride with the low fuel light constantly coming on (the Speed Triple registered a similar complaint during our 2007 street fighter test). Not a mystery is which bike is easier to fill, with the Bonneville splashing gas out on more than one occasion and the fuel cap fully detaching from the bike (easy to misplace for scatter brained test riders…).
Solid fit and finish round out an attractive, if Spartan, instrument package. The SE’s analog right-side tach teams well with the left-side speedo (the standard Bonneville not offering a tach). A fuel gauge would be appreciated, though there’s no real room for one, just a couple idiot lights and neutral, high-beam and turn signal indicator lights.
The Bonneville delivers a lot of bang for the buck. At $8399 for the SE and $7699 for the standard Bonneville, it’s 30-35% less expensive than the Ducati! I have to admit, however, that I’d spring the extra $400 for the $8799 T100 for the wire-spoked wheels alone. (The T100, which is unchanged for 2009 except for being fuel injected, is a much better fit ergonomically for larger riders as well.)
In short, the Bonneville SE is not a bad machine by any means. Power delivery won’t overwhelm newbies but still gets the Trumpet up to respectable cruising speeds. It’s a fun ride and an ideal bike for smaller riders. Faced against the Ducati, however, we imagine if it could talk, even the polite British Twin would acquiesce it does not compare with its sportier Italian rival. The Bonnie still keeps a stiff upper lip, however, secure in its role as an ideal starter bike or sharp-looking play bike for the casual weekend enthusiast.
This genre is difficult to categorize - part purpose-built metric dragster, part boulevard cruiser, part radical custom show bike, and a little Hip Hop style billet-bling thrown in for good measure. Metric super bikes such as the Suzuki Hayabusa or Kawasaki Ninja are a popular canvas from which these builders create their stretched and slammed customs. Some builders opt for the stripped-down, anodized, minimalist approach, while others never saw a metal bit that didn't deserve a layer of chrome. Different stokes for different folks, but any way you choose it, audaciousness is the prime mover of this rapidly growing niche in the world of motorcycles.

The last few years have been what could be described as something of a 'second coming' for Kawasaki.
A firm that once seemed content to tick-over with minor annual updates while the rest of the competition accelerated off into the wide, blue yonder have
given themselves a sturdy kick up the corporate backside of late, resulting in a healthy range of bikes with the scope to rival any other manufacturer.
Perhaps understandably, in this sports bike obsessed nation of ours, it's the headline bikes such as the ferocious ZX-10R; its nimble kid brother the ZX-6R
and the new 'considerably-faster-than-you' ZZ-R1400 that have been hogging all the media limelight.
Well, that's as maybe, but for those of you a little thinner in wallet and shorter in riding experience, you should be glad to hear that it's a case of
strength in depth for the green army in 2006, with the new ER-6f being a prime example.
Accessible performance, real world practicality and affordable insurance costs are, for the vast majority, just as important as three figure speeds and bar room boasts of unfeasible dyno figures.
Essentially a faired version of the ER-6n ('n' for naked, 'f' for faired) the f variant promises more potential for those looking to cover larger distanceswithout having to resort to rigorous neck-building exercises. But it's not just been a case of botching on a fairing and hoping the best. A fair bit of
thought has gone into the design process, resulting in a machine specifically tailored to suit its new role.
The front fork length has been increased by 10mm to compensate for the added weight and downforce generated by the new fairing and the horizontally-mounted,
offset rear shock has been tweaked accordingly. The net result is a slight increase in caster, trail, wheelbase and improved ground clearance which is helped
all the more by the stylish underbelly exhaust.
Having spent the day travelling since the wee small hours to our picturesque test location on the east coast of Sicily, the press briefing was refreshingly,
erm, brief with much of the focus centring on the motor. The parallel twin configuration isn't anything new, but interestingly it does appear to be making
something of a comeback in various guises other than the common or garden 500cc commuter bike.
Yamaha achieved moderate success with the 850cc (and latterly 900cc) TDM and TRX models in the UK, (though the TDM sold by the truck load in Europe) but up
until the arrival of the ER-6n and the eagerly anticipated BMW F800S and ST, the popularity of the parallel design seemed to be on the decline, with more
companies opting for the more fashionable four across the frame or vee-twin layout. So I guess they do have a fair point when they mention their 'unique
configuration'. Well, almost anyway...
Jumping on the bike, the riding position takes me by surprise a little with just how low it is. It's a slim bike too, meaning that for those a little short
in the leg, touching down both sides shouldn't be a problem (though taller riders will be pleased to hear that a higher seat is available as an optional
extra). Traditional handlebars also mean that there's plenty of scope to adjust the riding position to suit, meaning that it should be a case of
one-size-fits-all, which can only be a good thing. Confidence is a key word with the ER-6f and Kawasaki quite unashamedly highlight the fact that this is a
bike aimed at newer riders, riders returning to riding after a few years out or simply those looking for a mid-priced machine for anything from a Sunday
blast to the odd weekend away.
And it is an easy bike to ride. Heading out on to the unfamiliar Sicilian roads from our base camp in Taormina along the tight, cobbled streets that wind
their way through the scattered villages along the coast, the bike allows its rider to focus his attentions on avoiding the unpredictable drivers and errant
scooter riders that buzz around seemingly oblivious to what's going on around their Versace sunglasses, rather than worry about what the bike's doing.
Reading the map gaffa-taped to your tank. All in a day's work for Hoyles..
At slower town speeds, the motor feels smooth and fuels precisely. Unlike many vee-twins that tend to be lumpy and difficult to regulate at small throttleopenings, the ER-6f's delivery makes for a far more civilised and less stressful ride through town and traffic, with the generous turning circle making its
presence felt on more than one occasion, partly due to the tight town roads, but mainly down to the countless u-turns caused by my apparent inability to
follow a map. I blame the road signs, myself!
Carrying on a little further along the idyllic Mediterranean coastline, through picture postcard villages and up into the lush green foothills of the
imposing Mount Etna, the road opens out, finally allowing us to get out of the first three gears and giving us the chance to fully explore the bike's
performance.
To be totally honest, initially I'm rather underwhelmed. Rightly or wrongly, almost instantly I find myself comparing it to Suzuki's SV650 and by comparison
the Kawasaki feels a little bit flat. Stomp off the bottom end isn't anywhere near as torquey as the SV and for a while I'm left wondering what all the fuss
made of the ER-6n was about. A few corners later, I suss out how to ride it. While it may be a twin, the delivery and engine character are totally different
to the more traditional vee arrangement.
The art of saving money on your bike and your kneesliders..
Of course, the engine is essentially half a four cylinder motor, so the key is to rev it like one. The power comes in with a little more fervour at around
7,000rpm and keeping it buzzing higher up the rev-range rewards with reasonable drive off the turns, putting it on a par with the SV in terms of out-and-out
straight line performance, all the way up to a guesstimated top speed just shy of 130mph.
Making the most of the available power does mean that cog swapping needs to be clean and precise for spirited riding. Fortunately the little Kwak lets you do
just that. The gear lever connects directly to the gearbox shaft, meaning there is no slack to take up in the linkages as there aren't any.
But frantic hairpin-bashing isn't really what the 6f is all about. Cruising at a more sedate pace, taking in both the dramatic Sicilian scenery and spending
more time thinking about the bike than what may lurk the other side of a two-hundred foot precipice, I soon start to realise what it's good at. As it turns
out it's good, if not brilliant, at a little bit of everything.
but ninety percent of the time it quietly gets on with the job, providing a plush ride, complimented by the comfortable riding position and seat.The brakes work well enough to hoist the rear wheel off the floor with plenty of feel at the lever so there are no complaints there. There's also an ABS
option available (for an extra £400) which should be reassuring for less experienced riders.
Hoyles loves to get it up..
The 6f scores well in the practicality stakes, too. While the spec sheet reveals a relatively small fuel tank, the bike is incredibly frugal on juice - We
managed getting on for 120 miles before the light came on - despite spending much of the time thrashing around sinuous mountain roads. Expect well over 150
with a steadier throttle hand.
Well-placed bungee points should help with luggage and, with a whole plethora of genuine Kawasaki bolt-ons to enhance the touring experience such as a top
box that bolts directly in place of the side-mounted grab rails, large crash mushrooms, a higher seat and even smaller indicators to replace the hideous
original items there should be enough scope to personalise the bike to suit your type of riding.
Overall, while innovative in design, the ER-6f is still fairly simple. Bog-basic non-adjustable forks and brake calipers embrace trick petal discs and sporty
looking six-spoke wheels. From the old-fashioned (but very easy to read) clocks to the MotoGP style exhaust and cassette gearbox there's a fair mix of old
and new technology thrown together, though it has to be said that as a whole it does come together rather well both visually and on the move.

Way back in the mists of time and another century, Yamaha unveiled a concept bike at the Tokyo show. That
cobby machine was a concept bike called the MT-01. Those that saw it in the flesh were very impressed, as were
those that poured over the pictures in the world's motorcycle magazines.
Yamaha took the positive feedback and two years later delivered the BT1100 Bulldog in Europe, a bike supposed
to be as good as that concept machine. Despite some serious hype, the buying public were not that impressed,
and although some people fell in love with it, the sales figures showed it was not universally loved or liked.
Time therefore to accept that perhaps that original bike should come out of the concept file and head to the
sales brochure printers. However, when production costs are added into the profit and loss accounts system,
you have to compromise and perhaps make use of existing parts. I only mention the latter because the general
feedback from both the informed motorcycle community and those outside it was that the test machine looked
like a collection of spare parts!
Now as always, beauty is in the eye of the beholder, but the MT-01 certainly looks better from the right-hand
side where the striking V-Twin motor is showed off to its best advantage and the bike looks a little more
integrated. While the left-hand side with its oil tank on the side of the engine looks like a collection of
bits added on for functional and aesthetic purposes!But, when you start analyzing this bike that was built for "more mature experienced riders that wanted
something with some soul," you begin to see where the parts came from and realize it is really a bit of a
parts bin special!
Take the engine for instance, a long-stroke 1,670cc air-cooled OHV powerplant and the biggest V-Twin ever
built by Yamaha. It is based on the proven 48-degree V-Twin unit that is featured on the extremely successful
US-market model, the Road Star Warrior.
Yamaha claims that although it is outwardly similar in appearance to the cruiser powerplant, the MT-01 engine
has been considerably re-worked. (One of the main development goals for the MT-01 engine designers was to
create a powerplant with maximum intake and exhaust efficiency in order to achieve remarkably high levels of
low- to mid-range torque.)
The MT-01's bore and stroke dimensions are 97 x 113mm, and the four-valve cylinder heads feature a pentroof
design and twin spark plugs. Cylinder walls are ceramic-composite plated for reduced frictional losses and
enhanced heat dissipation, and this massive V-Twin runs with durable forged pistons and a compression ratio of
8.36:1.

One of the most significant features on the MT-01 engine is the adoption of a new lightweight crankshaft
assembly, which uses a new flywheel with less mass. The lighter crank makes for instant pick-up and rapid
acceleration, and completely transforms the performance characteristics of this massive V-Twin engine.
The engine is fed by a 40mm downdraft-type twin-bore throttle body which is mounted laterally so that it fits
into the narrow space between the 48-degree Vee of the air-cooled cylinders. This system ensures instant
throttle response and strong standing start and roll-on acceleration. A new 7-liter downdraft-type air cleaner
box featuring a variable air intake valve system has been developed for the MT-01, and this large-capacity
unit gives reduced air-flow resistance, which ensures an efficient intake system.
At the other end of the process, we see Yamaha's EXUP exhaust system moving to a new home. It has in the past
been confined to four-cylinder supersport machines, but now this torque-boosting system is used for the first
time on a twin-cylinder bike. But due to the exhaust forces and pressures involved on the MT-01 engine being
greater, a much stronger valve has been developed to cope with them. This compact system features the variable
valve positioned where the two exhausts merge into one, and this constantly adjusts the internal diameter of
the exhaust to match engine rpm.Yamaha claims that a great deal of effort has been made to ensure the MT-01's
throbbing exhaust note and massive power pulses would not be diluted by noise and emissions regulations.
Therefore, the catalytic converter features a 'hot tube' positioned immediately after the EXUP valve, while
the honeycomb-type catalytic converter is placed at the beginning of the titanium up-mufflers. By positioning
the components in this way, the massive power pulses and the deep, powerful exhaust note are maintained and
the exhaust gases still clear Euro2 emissions standards.
The system ends in dual titanium mufflers which are made a focal part of the overall styling along with the
big-bore exhausts with their large radius curves on the right of the engine. (The silencers are equipped with
a forced-cooling fan that ensures efficient heat dissipation to help keep the rider and passenger cool in
traffic.)
A five-speed gearbox with relatively high gear ratios for a relaxed feel is driven through a newly designed
compact clutch assembly. Final drive to the rear wheel is via a heavy-duty chain running along the right side
of the swingarm, unlike the Road Star Warrior's engine which features a transfer unit connected to a belt
drive running along the left side. Eliminating the bulky transfer unit has allowed the chassis designers to
develop a short wheelbase chassis with a relatively long swingarm for neutral handling characteristics.
Moving onto the chassis itself, this was newly designed to ensure that the engine took the main attention when
the bike was viewed from the side. Yamaha's chassis development team therefore had to create a minimalist
structure that would also give good handling characteristics. They achieved this by using the very latest
controlled-fill die-casting technology, an exclusive process patented by Yamaha and first used on the YZF-R6.
It offers many advantages over conventional technology and has opened up new possibilities in frame design,allowing the creation of lightweight, extremely strong structures with an idealised rigidity balance along
with a high-quality finish. In this case the CF die-cast aluminium frame is made up of just two cast parts
(left and right) that are bolted together at the head pipe assembly and at the swingarm pivot. Bolted to the
main frame is a two-part cast and moulded aluminium downtube, and the whole main frame structure is totally
weld-free.The engine is then bolted to this using an eight point rigid-mount system, making it a fully-stressed member.
This has helped the designers keep overall frame dimensions to an absolute minimum by making the lower area of
the engine as compact as possible. This has allowed the use of a long cast aluminium swingarm, while at the
same time retaining a relatively short wheelbase of only 1,525mm (60.0-inches).The combination of a short
wheelbase together with a 25-degree caster angle, 103mm trail, a 47/53% front/rear weight distribution work
together to give the MT-01 a neutral and stable ride whilst being relatively responsive to rider input.
At the front, the bike is supported by fully-adjustable R1-derived upside-down front fork. The 43mm unit is
fully adjustable for preload, as well as rebound and compression damping, and offers 120mm of travel. The rear
shock is mounted almost horizontally beneath the rear of the engine to help improve the mass centralisation
and give a lower center of gravity. Like the front suspension, the rear shock is adjustable for preload and
rebound and compression damping.
The bike rolls along on stylish new four-spoke cast alloy wheels which weigh approximately the same as the
traditional three-spoke design. These are shod with a 120/70-17 front radial tyre and an extra wide 190/50-17
rear radial tyre for better of traction.
As befits a machine of this size and status, it is equipped with high-specification YZF-R1 type brakes. Dual
320mm floating front discs are slowed by one-piece 4-piston radial-mounted callipers backed up at the rear by
a single 267mm disc. (The radial mounting system was originally designed for sports machines and it helps
minimize calliper distortion under heavy braking to give enhanced braking action and accurate rider feedback.)
Moving onto the overall design, the 15-liter fuel tank is long and low, fitting in neatly with the curves of
the bike when viewed from the side. When viewed from the front, it has a very distinctive look thanks to the
multi-reflector headlight unit. This actually consists of two lights of different diameters which project a
wide, powerful low and high beam. At the back it is a similar story with an LED taillight sitting between the
massive twin titanium up-mufflers. This features a series of unequally spaced LEDs that accentuate the bike's
unique look.
Like many machines these days, the MT-01 is supported by plenty of accessories from Yamaha. They are divided
between performance components and lifestyle items such as clothing, sunglasses, watches etc. Performance bits
consist of fly screens, air intake scoops and styling accessories. Also included are a single seat kit and
carbon heat shields that work in conjunction with the exhausts that are available from the tuning kits and
which have been developed in collaboration with Akrapovic. In total, Yamaha offers three levels of tuning kits
of which the first level is street-legal and the other two levels are for track-use only.
But, if from that you think that you are going to get a tire-shredding beast that will outperform sports bikes in the traffic-light GP, you would be wrong. This is no V-Max replacement, despite what you may have read elsewhere!is, however, a whole new breed of machine that has popped up as a halfway house between a sports bike and
cruiser, with the looks of a naked musclebike. It must be said that it is lots of fun, but it is not one of the world's most practical of mounts, despite its excellent roll-on acceleration traits.
A clue to its character can be gained once sitting astride the relatively low machine. The simple round-facedcombined tacho and speedo with its warning lights inset shows its minimalist nature. With a redline set at just 5,500 rpm it is certainly not a bike that is going to thrive on revs.
Fire it up and you get the lazy thump of a big V so beloved by the Harley brigade, along with a relatively sporty exhaust note. However, selecting the first of five gears and feeling the ultra-smooth engagement and
take-up has the senses somewhat confused - very un-American!
You soon realize that you might just as well go straight to the top and forget about the rest of the gears;
and were it not for the high gearing making it impossible to hold 30 mph in top, you would have a superb
almost automatic bike. However, once above 40 mph this can be done and the ride enjoyed, unless you want to
make serious progress or find a set of bends you wish to attack with some gusto.
No, you did not misread things. This 240-kg (529-lb) monster does what Yamaha claims on the box: it handles.
Okay, it can't really take on a sportbike, but it will show a clean pair of silencers to a badly ridden one,
and providing you keep your riding style smooth it will not dig in or ground out. Keep the rev counter between
2,000 and 4,000 rpm and the bike will keep up a pretty respectable pace, and the vibes coming up from the motor will not intrude into your comfort zone whilst you wipe the smug looks off some riders.The positions of the handlebars, seat and footrests give a natural, slightly forward-leaning riding position that distributes your weight fairly evenly through each point of contact with the bike. This relatively relaxed seating position, combined with the very slim fuel tank, allows you to keep going as long as there is gas in the tank, normally around the 125-mile mark.Certainly, comfort is not an issue, Even adding weight failed to phase the braking system that was able to cope with whatever I threw at it under
normal riding, likewise the suspension system. On standard settings it did all I wanted and it seemed pointless trying to adjust everything just to fine-tune it to the 'enth degree, which may have dialed out the general comfort of the bike.
What I did do, however, was to have the bike tested on a dyno to see just what the engine was kicking out in the way of torque. With 112 lb-ft at 3,800 rpm showing on the graph with a hot engine (and 88.8 bhp), it confirmed that my riding impressions were correct and Yamaha had achieved their goal of building a real-world
rideable bike.This is definitely a machine that can put a smile on your face on less populated roads. Likewise, it is not
too uncomfortable at speed on the freeway and it is nimble enough to be a reasonable commuter that happily
deals with traffic, providing you do not sit in it for too long when heat becomes an issue.
Where the MT-01 falls down is that it does not really know what it wants to be. It is not a V-Max
straight-line tire shredder, it is not a Buell and it is not a Bandit. It is in a class of one, which could be
a big plus point as well as a negative. Sadly despite all the hype about soul, it - like most Japanese V-Twins
- misses the point a little.But this bike's biggest downfall is its price tag in England. A bike that retails for 9,495 pounds (US$17,000,
though it would be priced closer to $14,000 if sold in America) will probably put a lot of riders off from
throwing a leg over one for a test ride.
