The Yamaha Wolverine X4 engine utilizes YCC-T(R), a drive-by-wire system that converts the driver’s commands into precise throttle control. The X4 comes with Real World Tech for impeccable engine response as well. The Throttle response is further improved thanks to a new ‘high-response’ servo motor for ultra-fast throttle application, 12-hole fuel injectors and a high-volume airbox with two-stage air filtration.
