Key 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 ?rst production motorcycle with a ?y-by-wire throttle system—for ?awless response under all conditions.
* YCC-I, Yamaha Chip Controlled Intake, introduced in 2007 on the R1, is now used on the R6 to vary intake tract length for excellent cylinder ?lling and a broader powerband. On the higher-revving R6, its bene?ts 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.


New for 2008:



* Over 50 friction-reducing strategies have been employed inside the engine, including the use of wider crank bearings.
* Upgraded fuel injection mapping for the YCC-T dual-injector system complements the higher compression ratio for great throttle response and reduced engine braking.
* A magnesium subframe removes weight from the rear of the motorcycle for increased mass centralization.
* All-new frame takes handling to the next level, allowing more precise turn-in, greater corner speed, and tighter exits. Thicker headpipe-headstock and swingarm pivot area walls, and elimination of the frame crossmember, help achieve perfect balance.
* New swingarm has internal ribs added, and extruded section is now forged to work with the new frame.
* Revised outer fork tubes, a new lower triple clamp, and increased fork offset provide highly tactile front-end feedback.
* Moving the rider and bars forward and slightly lower enhances braking and turn-in performance. Clip-ons are also lower and re-angled.
* Front discs are 310 x 5mm instead of 4.5mm for increased cooling qualities.
* Increased fork height adjustability and rear ride-height adjustment range accommodate a greater range of riders and tires.
* Revised bodywork results in even greater aerodynamic efficiency.


Engine:


* YCCT—Yamaha Chip Controlled Throttle—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.
* Back torque-limiting slipper 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 bores mean 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.


Chassis/Suspension:


* Deltabox aluminum frame incorporates GP thinking in terms of engine positioning and rigidity for the ultimate in 600-class handling.
* Lightweight aluminum swingarm pivots high in the frame, for increased anti-squat 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.


Additional Features:


* Built-in lap timer is controlled by a right handlebar switch.
* Multifunction digital and analog instrumentation features: programmable shift light, digital speedometer, analog tachometer, dual tripmeters with miles-on-reserve function, odometer, water temp gauge and lights for neutral, high beam, low fuel and turn signals.
