2009 Yamaha YZF-R6Key Features:
Light, powerful and bristling with knowledge gained from years of racing, the YZF R6 is the most advanced production 600cc motorcycle Yamaha - or anybody else - has ever built.
The YZF-R6 was the first production motorcycle with a fly-by-wire throttle system for flawless response under all conditions.
YCC-I, Yamaha Chip Controlled Intake, is used on the R6 to vary intake tract length for excellent cylinder filling and a broader powerband. On the higher revving R6, its benefits are even more pronounced.
Slipper-type back torque-limiting clutch greatly facilitates braking/downshifting from high speed.
The YZF-R6 achieves fuel economy up to an estimated 40 mpg** with a fuel tank that holds 4.6 gallons of gas.Features & Benefits
The Engine Control Unit (ECU) has remapped YCC-T settings to optimize power output in each gear, to achieve smooth, linear power delivery out of the turn, with excellent overall drivability.
Compact, lightweight 67 x 42.5mm 599cc DOHC 16-valveliquid-cooled titanium-valved four-cylinder has a compression ratio of 13.1:1, for great response. Domed pistons with valve cutouts produce a compact combustion chamber.
Fuel injection mapping for the YCC-T—Yamaha Chip ControlledThrottle dual-injector system complements the high compression ratio for great throttle response and reduced engine braking.
YCC-I—Yamaha Chip Controlled Intake electronically variesintake funnel length for an amazinglyf broad, smooth powerband.
A magnesium subframe removes weight from the rear of themotorcycle for increased mass centralization.
YCC-T uses a powerful ECU and multiple sensors to provide perfect, smooth engine response and optimal power whenever the throttle is twisted under all conditions.
Twin-injector fuel injection: shower-type injectors above each intake funnel help achieve optimum fuel atomization at high rpm.
Slipper-type back torque-limiting clutch greatly facilitates braking and downshifting from high speed. Close-ratio six-speed transmission delivers seamless power and maximum acceleration.
GP-style titanium muffler contributes to mass centralization and contains EXUP® for a broad powerband, spot-on injection and emissions compliance.
Linerless, direct-plated ceramic-composite cylinder boresmean greater heat dissipation for consistent power delivery and reduced friction.
Cool magnesium valve and engine covers are light and stylish.
Direct-ignition coils, dual-electrode spark plugs and high-output magneto deliver extremely accurate, reliable firing.
Deltabox aluminum frame incorporates GP thinking in terms of engine positioning and rigidity for the ultimate in 600-class handling.
A die-cast swingarm pivots high in the frame, for increased antisquat effect and mid-corner stability. TZ-type chain adjusters ease rear tire changes.Four- way adjustable (preload, high-speed compression, low-speed compression and rebound damping) inverted fork with 41mm tubes increases freedom in setting up for street or track use; soak up the bumps and resist bottoming when braking.
Four-way adjustable (preload, high-speed compression, low-speed compression and rebound damping) piggyback rear shock delivers exceptional rear wheel tracking and stability.
Dual 310mm front disc brakes use forged one-piece radial-mount calipers and radial-pump front master cylinder with adjustable lever for astounding braking power and feel.
The casting technique for the five-spoke 17-inch wheels makes the rims light and strong, not to mention wickedly cool-looking.
