Yamaha Power Valve System (YPVS).
Mechanical power valve system delivers effective exhaust timing throughout the entire rev range
Provides excellent power and torque characteristics
Boosts compression ratio and power output
Delivers responsive acceleration just as the rider intends
Slit-shaped valve on the side of the exhaust port operates in response to engine rpm
In low-to-mid-rpm range when exhaust timing is slower, valve moves to cover the top part of the exhaust port
In high rpm range when quick exhaust timing is needed, valve recedes and exhaust port is fully uncovered
Shifting is reduced due to broad powerband
Crankcase reed valve induction and 28 mm Keihin flat-slide carburetor.
crisp, seamless throttle response across the powerband
design features spacer-style reed valve intake for improved gas flow
Lightweight, forged piston.
