998 Genesis Turbo Engine
The 998 Genesis Turbo Engine is unmatched when it comes to delivering incredible power. Every engine component from intake to exhaust is dedicated to producing uncompromised performance, earning the respect and reputation as the industry's highest achiever.
YSRC High Performance Clutch System
The YSRC primary and roller secondary clutches are calibrated for durable, cool operation. They efficiently harness and transfer the massive torque produced by the Genesis Turbo to the track, all while minimizing drive belt wear. The primary shifts out aggressively to use all of the power while the roller secondary is quick to back-shift and provides additional ratio through its oversized sheaves for continuous acceleration.
Engine Braking Reduction System
The effect of 4-stroke 'engine braking' when the throttle valves are closed has a significant impact on handling and ride character, so Yamaha developed a special system which employs the ISC (idle speed control) circuit and ECU map that uses throttle valve movement and RPM information to reduce negative intake pressure during deceleration.
