The relaxed geometry, tighter rider triangle, tuned-for-low-to-mid powerband and R-bike styling make the FZ6R a notable addition to Yamaha’s sportbike
The relaxed geometry, tighter rider triangle, tuned-for-low-to-mid powerband and R-bike styling make the FZ6R a notable addition to Yamaha’s sportbike line-up.
Yamaha breaks down its “sportbike” category into three sub-classes: Supersport, Sport and Sport-Touring. Their research says 60% of its first-time buyers choose a Supersport bike like the R6 and R1, both of which aren’t exactly newbie friendly. Just 32% of these consumers chose an FZ1 or FZ6 from the Sport category.

2009 Yamahas YZF-R1 And FZ6R
While the company's flagship sportbike was heavily updated in '07, Yamaha has further revamped the R1 for '09. The highlight is the use of a "crossplane" crankshaft that spaces the journals at 90-degree intervals as opposed to the traditional 180, giving the engine an uneven firing order. The design is based on experience from the M1 MotoGP program and is said to provide a "more linear driving force in response to throttle movements and more linear controllability when exiting a corner for maximum acceleration."
In a typical engine, vibration is caused by the piston moving up and down, accelerating and decelerating with every stroke. Counterweights on the crankshaft are used to offset some of the weight of the piston, ring and connecting rod assembly, but this simply transforms some of the up/down inertia to a fore/aft direction as the crankshaft spins. Multi-cylinder engines allow each cylinder's inertia to be offset with another's; for example, in an in-line twin-cylinder engine, the rising piston nicely offsets the falling piston, eliminating primary vibrations-those acting at crankshaft speed. Because the cylinders are separated, however, a rocking couple is created. A four-cylinder engine with a conventional crankshaft eliminates that rocking couple because each set of rocking pistons is offset by the second set. There are still secondary vibrations and moments-those acting at twice crankshaft speed-present in a conventionally laid out four-cylinder engine, and these are sometimes dealt with by a small shaft rotating at twice crank speed

Suzuki GSX-R1000
To the team of Suzuki engineers responsible for the GSX-R1000, Own The Racetrack is not just a slogan,it is a way of life.
It's a life dedicated to making the most successful open-class motorcycle in the history of production-basedracing even better. The key is the motorcycle's ability to do precisely what the rider wants, when the riderwants, how the rider wants. Accelerate, brake, corner, repeat. Make it easier for the rider, and the resultswill show.
Once again Suzuki has raised the level of open class sportbike performance. The 2007 Suzuki GSX-R1000,it's the reason why Suzuki riders Own The Racetrack
