Yamaha R1


electronics package could be better too as we didn’t find Yamaha’s D-SMS adjustable throttle map system to be very useful. This piece of electronics allows the rider to adjust the sensitivity of the throttle. By default the engine is in ‘Standard’ mode. ‘A’ mode increases the sensitivity of the throttle and ‘B’ decreases it. Our testers preferred ‘Standard’ or ‘B’ mode as ‘A’ mode made the engine feel like it surged too aggressively during delicate throttle situations like moments after hitting the apex of corners. We understand that the objective is to offer options to the riders but we would prefer to have more useful options than the R1 maps offer.

“The Yamaha feels okay… It’s actually pretty similar to the other Japanese bikes ergonomically,” states Gauger. “The dash is easy to read and the riding position isn’t cramped, I just didn’t really like how wide it felt. It was also sort of heavy too, which made it a bit more-tricky to manhandle during low-speed corners and maneuvering it in parking lots.”

A tall first gear makes escaping stop lights on the Yamaha YZF-R1 harder than you’d expect from a liter bike. It requires a fair amount of clutch slippage to get it rolling and that made it difficult to get a perfect launch during drag strip testing. Fortunately the clutch lever action is light and offers good feel which offsets the fact that you have to really drag it to get a good launch. The rest of the drivetrain components including the six-speed transmission, final drive gearing (17/47) and slipper clutch were all rated highly and tied the Honda for second-highest honors.

In our acceleration tests the Yamaha registered a 0-to-60 time of 3.08 seconds which put it last along with the hard-to-launch 1198. Granted both those bikes and the RC8R all took more than three seconds to reach 60 mph. At the drag strip it finished the quarter mile in 10.38 seconds at 139.3 mph, which once again had it languishing near the back of the pack along with the Italian and Austrian Twins. We attributed to its modest engine power output paired with excessive weight and tall first gear to this showing. It gearing was very good for the track this time around, but it hurt the Yamaha in head-to-head performance tests.

Our Dynojet 250i revealed that the R1’s engine, despite being the most popular in terms of exciting the rider’s senses, ranked toward the back of the class in outright power. At 5000 rpm it’s cranking out the lowest amount of torque before eventually catching up with the Kawasaki, BMW and Suzuki for a moment. Shortly thereafter it belts out its peak torque of 75.65 ft-lb at 9000 rpm and then it begins to taper off. The Yamaha R1 does finish ahead of the high-strung ZX-10R in the torque battle but it doesn’t have the same horsepower to make up for it that the Ninja does. The horsepower curve mimics the Kawasaki at lower rpms but it eventually peters out early with its second-lowest in class total of 152.13 hp at 11,800 rpm. Only the 1198 makes less power but again, keep in mind that the 1198, RC8R, CBR, GSX-R and R1 are only five horsepower apart. It’s the pesky Ninja and S1000RR that make the rest of the field seem feeble with their 163 and 183 horsepower figures respectively. Like we mentioned already, what the R1 lacks in outright performance it sure makes up in personality.

In Yamaha’s defense it is operating with the second-quietest exhaust note of 79 dB as measured at idle and the quietest tune of 94 dB at half of max rpm (6750). Many of our testers were raving about how awesome the engine sounds with its guttural roar more related to that of a small-block V8 than a sport bike. Equally as pleasant is how well balanced the engine is, virtually devoid of annoying vibration except at very low rpm, the R1 never makes your hand go numb because of unwanted vibes.

Perhaps it was our heavy throttle hand, but the R1 registered the worst fuel mileage of the test and even finished behind the 200cc larger Twins. We recorded a 28.6 mpg average which equates to a range of 137.2 miles. For comparison the GSX-R was the second-worst Four-Cylinder and it registered 33.9 mpg. The ZX with its small fuel tank and average fuel economy offers the next lowest range at 154 miles, 17-more than the R1. Again, it’s hard to stay off the throttle on the Yamaha though – that engine just sounds so damn good that we would be willing to give up a few mpg just to hear it howl.

BMW R1200GS


BMW R1200GS
BMW refurbished its iconic Flat Twin Boxer with a new cylinder head and not an increase in displacement.

The new DOHC radial valve head delivers an extra 5 hp and 3 lb-ft of torque, as well as a 500 rpm higher redline.
It was expected that BMW would debut an upgrade to its iconic Flat Twin Boxer for the 2010 R series. Now the details are revealed, as 2010 motorcycle info leaks prior to the upcoming EICMA Milan Bike Show. Here’s what the spec sheets and PR machine say about the new Boxer.

Same Displacement: No, the Boxer is not gaining any CC. Bore and stroke is identical at 101 x 73mm with the 1170cc displacement unchanged.

New DOHC Cylinder Head: The 2010 Boxer cylinder heads feature cylinder head upgrades first used on the HP2 Sport. The DOHC design sources two chain-driven camshafts, with each camshaft controlling both an intake and exhaust valve in the radial four-valve head. The valves themselves have changed, with diameter increased on both intake (1.42-1.54 inches) and exhaust (1.22-1.30 inches), with valve lift also increased. Compression ratio is unchanged at 12:1, however, a new combustion chamber shape necessitates the use of red-designed cast-aluminum pistons.

Larger Air Intakes: New black throttle butterfly manifolds are larger, up 0.12 inches to 1.97, and work with redesigned intake manifolds and air filter element.

Performance Gains: All the motor tweaks add up to more power and a higher-revving Twin. Peak horsepower claims jump 5 hp to 110 total, with torque up 3 lb-ft to 88. The peak outputs come at a higher rpm, a respective 7750 (up 250 rpm) and 6000 (up 500 rpm). The redline jumps an extra 500 rpm as well, to 8500. Overall, BMW claims the modifications “provide a significantly more homogeneous flow of power and torque throughout the entire speed range.”

Throatier Exhaust: The exhaust system looks identical to its predecessor, but BMW promises a sweeter tune with a new internal structure to the rear can, along with an electronically-controlled exhaust flap. BMW describes the new decibels as “a particularly throaty Boxer sound naturally in full compliance with legal standards.” Naturally.

The new Boxer motor headlines the upgrades to three 2010 R-series machines announced by BMW: the popular BMW R1200GS and its Adventure sibling, as well as the R1200RT tourer.

Motion exposes Ducati’s go-fast intentions, and for the Diavel, that begins with the motor. Strapped to Hypercycle’s dyno the Cromo produced 134.5 rear-wheel horsepower at 9400 rpm and 80.1 ft.-lb. of torque at 7900 rpm from its Testastretta 11° engine. Twist a handful of right grip and the deeply curved seat immediately makes sense. While it tends to lock its rider into a single position, the backstop it provides when unleashing the engine’s potential is welcome support considering the bike’s upright seating arrangement.

In the hands of MO’s dragstrip specialist, Duke put the Diavel through the lights at Famoso Dragway outside Bakersfield, California, in a very respectable time of 10.32 seconds at 131.29 mph. Corrected for temperature and air pressure, the ET converts to a seriously quick 9.95-second pass. Yes, we did run the Cromo against the VMax but we’re withholding that information for our upcoming shootout between these muscle-bike beasts.


The Diavel is fairly easy to launch and gets out of the hole quickly.


On the street and in the corners the Diavel Cromo blurs the lines between cruiser and sportbike. “Despite its cruiser pretense, this is one factory custom that doesn't need to shy away from a twisty canyon road,” Duke says. Despite its conservative rake and trail figures and its wide swath of rubber out back, initial lean-in is easy to achieve, but it’s leveraging that 240mm wide tire to its edge that’s trying.

“When you get it leaned over, the front feels like it's going to slide out from under you,” says Siahaan. “It won't, but you have to slowly work up to that level of trust with the Diavel.”

Another eminent performance attribute are the Diavel’s brakes. “Its Brembos are notably strong, but their initial bite might be a little too abrupt for anyone accustomed to typical cruiser brakes,” notes Duke.


The passenger grab handle disappears beneath the passenger seat when not in use, as do the passenger footpegs which discreetly fold away.


Included in the Cromo’s asking price is an array of electronic gadgetry such as ABS, DTC, riding modes and ride-by-wire throttle, while suspending the bike is a fully adjustable 50mm Marzocchi fork and a Sachs progressive linkage monoshock, both fully adjustable. As mentioned earlier, these components are identical to those on the lesser expensive standard model Diavel.

For a more detailed assessment of the Diavel’s performance read Pete Brisette’s full review, and stay tuned for our forthcoming shootout against the VMax.

For now, Duke sums the Diavel up best, saying it “impresses as much for what it isn't than what it is. It's not a typical cruiser nor is it a typical Ducati but a hybrid of cruiser and sportbike that delivers a pleasingly unique riding experience. There’s nothing else quite like it.”

Big Dog




Riding all day at freeways speeds is not only possible but can even be enjoyable. However, when you come to the off ramp, you better chomp on the full set of 4-piston PM's and bring the 'ol girl down to first gear and be happy they moved the kickstand rearward this year, because the ground clearance is pretty much what you'd expect, non-existent! Lean angle, what's a lean angle? Don't even bother hitting the twisties on a bike like this. Most guys stick to wide sweepers and freeways when enjoying the 'Ol Dog, instead of fighting their way through a couple hundred turns at 15mph.

As the only rigid framed chopper in the Big Dog lineup [The Pitbull model doesn't have the 8" stretch to its downtube like the Ridgeback and is 12" shorter in the forks.], most of the time the Ridgeback left me wishing it was the softtail version. The Big Dog "Chopper" has pretty much the same look and features as the Ridgeback, but includes a soft-tail type frame and rear suspension. If you want the comfort to ride from SoCal to Sturgis, the "Chopper" is your best bet and I'm anxiously waiting for a chance to prove it! The "Chopper" and "Ridgeback's" low-slung saddles put the rider "behind" the gas tank, sparing you from much of the windblast, kinda like a dual-purpose fairing. This helps to ease the usual strain that an ass-low, hands-high, feet-foreward riding position causes at sustained freeway speeds. Another "comfy" feature I found during my stint riding this beast, is the saddle length and foot-pegs. Although there is no pillion seat to speak of, the stock passenger pegs come in handy for lifting your butt off the saddle in a jockey type riding position, saving your spine on choppy roads. Slide back a few inches and settle on the high-point of the saddle for the thickest cush. When you do find a comfortable long distance riding position, you still need to be mindful of your fuel mileage.

When you do find a comfortable long distance riding position, you still need to be mindful of your fuel mileage.

The petcock's reserve position leaves about as much gas as you'll find in a Bic lighter. When you switch to reserve, hit the turn signal and find gas ASAP. One block of stop and go cruising on the Sunset strip cruising will deplete the reserve and leave you parked, if you're not watching for filling stations, I speak from experience.

Now that your 86 Testarossa & Miami Vice suit have gone out of style, you've latched onto the leather boy look of the HD crowd. However, your matching chaps and tassles actually seem to make you feel like just another midlife-crisis non-conformist strictly conforming to the pseudo-trendy fashions of the herd. Panic, horror, despair! What will you do? The folks at Big Dog Motorcycles think they've got an answer for you.
Personally, I think you're an idiot, if you actually go out and buy one of these pigs, but I'll be the first to admit that I simply "don't get it". On the other hand, EBass, our resident self-proclaimed "poseur", seems to think that Choppers (and probably disco, tattoos, cigars, piercings and Howdy Doody) are the cutting edge of "cool" and just the ticket to elevate him to moto-god status. Didn't somebody once say: "A sucker is born every minute"? Anyway, EBass decided it would be a good idea to use the MO name to wrangle one of these $27,000 rolling codpieces from a chopper manufacturer. Unfortunately, EBass decided to sell the story to another rag, so even though MO was legally responsible for the bike, we didn't really get anything out of it, aside from Fonzie using it as a prop to shoot nudie pics of a lady friend (see below for the rated-PG versions). Anyway, I digress... I must admit I was more than a little curious what a modern "state of the art" chopper would ride like and I did get a chance to spend some time on the Ridgeback, before it went back to its kennel.

Really oversquare for a cruiser, at 88 x 66.2mm, it's actually a free-revving, enjoyable engine to play with, coupled to an agreeable, wide-ratio five-speed box and a nice, light clutch. Throw it in fourth or top gear (fifth), and it's easy enough to burble along from 30 to over 100 mph with very little fuss. A lone, 36mm Mikuni carburetor with an accelerator pump, no less, responds to the whip nicely once past the typical off-idle glitch (which one small washer shoved under the needle would probably fix).

This one's a 55-degree, single-crankpin twin, but with a counterbalancer and rubber mounts. It runs plenty smooth, vibration is not a problem, and in truth the ride's not at all bad. There's a linkage-mounted shock hiding underneath the hard-tail looking swingarm, with four inches of travel,and an also nicely damped 41mm fork. Along with the fat tires and a thick, nicely supportive seat, the Vulcan gives up a surprisingly suave ride. Get aggressive going round corners, though, and the Vulcan's pegs start dragging a bit early even by cruiser standards.


Other than that, what's not to like? Eee, well, we realize that beauty is in the eye of the beholder, but nearly everybody who beholds this beauty comes away wishing they hadn't. It's a Harley from Toon Town. Those "dual shotgun exhausts" might be cool if not for the black things in the ends which so obviously reveal the true diameter of your exhaust flumes; the motorcycle equivalent of getting caught stuffing socks down your pants. The front fender is a tire mullet.

Maybe it's not even the individual parts as much as the disharmonious way they all fit together? This is one ugly motorcycle, but one which, in its defense, looks good in family photos next to sister 800 Drifter and cousin 750 Vulcan.

But hey, that's just my opinion. My boy won't be seen in shorts if they don't extend past his knees. Tattoos and piercings and shaving your head are "in." I always liked Camaros and still do. I'm afraid of Julia Roberts' lips. Rap is a waste of oxygen. I'm hopelessly out of touch. If you like the Vulcan, you should get one; functionally it's a great personal transportation unit.

Suzuki introduced their Volusia 800  is smooth, but too cold blooded. Takes a looong time to warm up, even with full choke. Bars felt wide, but wasn't uncomfortable. I like the digital odometer and clock stuff. Brakes could be better, but modulated well. It has a solid transmission.

Suspension felt really soft, but that wasn't surprising. Chassis feels solid (though it should considering it is made of metal.) The only thing not to like? The rather bland styling. It gets lost in the crowd.

The forks are set out at a 33° angle and the shock works through a link-type system to smooth the ride over the Volusia's 65.2 inch wheelbase. Seven positions of preload adjustability are available out back, though there's no concession made for either rebound or compression adjustments at either end.

The thing that so many of us like about the smaller-displacement cruisers is the way they rev, and this Suzuki will wail. There's none of that rev-limiter cutting in seemingly right after you've released the clutch and get underway. The Volusia likes to run, and by the time you realize there's no hard limiter to bump into (the Volusia uses a soft limiter) you've already grabbed another gear and are on your way.

Spec Byson





The other difference is the rear tyre size of the Spec Byson which is a 120 section one. The Indian Yamaha FZ-16 sports a rather flat shaped 140 section radial tyre. The shape of the rear tyre of the Byson is also rounder in shape compared to the flatter 140 section on the Indian FZ.

The Yamaha FZ doesn't have the best reputation for fuel efficiency among 150 cc bikes in India. The culprit could well be the broad contact patch of the wide tyre of the FZ.
