TOP FEATURES ENGINE Torquey CP2 Powerplant Yamaha's proven 689cc liquid-cooled, inline 2-cylinder DOHC fuel-injected CP2 engine delivers excellent power and performance throughout the rpm range for an exhilarating ride and a true supersport experience. Its 270-degree crankshaft delivers linear torque for exciting acceleration and limited vibration. Linear Torque with Smooth Acceleration The all-new YZF-R7 boasts a 270-degree crankshaft that delivers a tactile experience of pulse and acceleration with limited vibration. The CP2 engine provides the rider a linear-feeling, direct connection from the throttle to the rear wheel. All-New A&S Clutch A first for Yamaha's CP2 platform, the all-new Assist and Slipper clutch reduces clutch lever force while providing seamless downshifts and a controlled feeling over the bike's engine braking. This helps make the supersport riding experience more accessible to more riders. For fast and smooth upshifts, an optional Quick Shift System (QSS) is also available on the YZF-R7. Quick Shift System for Smooth Upshifts An optional Quick Shift System (QSS) can be paired with the YZF-R7 to help provide speedy, smooth upshifts. When the sensor on the shift rod detects movement in the gearshift lever, adjustments are made in the engine output according to ECU calculations to instantly cancel out the drive torque of the engaged gear to promote swifter gear changes.
