Yamaha YZF-R6 599cc DOHC 16-valve liquid-cooled

Yamaha YZF-R6

* 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.

Engine:

* Compact, lightweight 67 x 42.5mm 599cc DOHC 16-valve liquid-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 Controlled Throttle dual-injector system complements the high compression ratio for great throttle response and reduced engine braking.

* YCC-I—Yamaha Chip Controlled Intake electronically varies intake funnel length for an amazinglyf broad, smooth powerband.

* A magnesium subframe removes weight from the rear of the motorcycle for increased mass centralization.

* Fork height adjustability and rear ride-height adjustment accommodates a great range of riders and tires.

* 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 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.
