A new slimmer, flatter and more compact body eases rider movement for improved control, including more seamless, rounded features from seat edges and side covers to a more narrow fuel tank and front shroud. The rider triangle is also improved with increased legroom between the seat and footpegs, and revised handlebar position for a more natural posture and enhanced rider comfort.
A completely redesigned aluminum bilateral beam frame provides just the right amount of strength and flex for the perfect balance of stability and cornering performance. The result is a better handling machine with lighter feel, more agility and increased traction allowing the rider to enter corners with greater confidence and more line choices.
The all-new Traction Control System communicates wheel slip to the ECU, tuning the engine to maintain ideal rear wheel traction. Three levels can be selected: HIGH, LOW or OFF. The updated Launch Control System now features an rpm limiter which can be adjusted in 500 rpm increments between 6,000 rpm and 11,000 rpm for optimized launches when the gate drops. Both systems are controlled through the Yamaha Power Tuner App.
A large 270mm front brake rotor is coupled with a Nissin caliper to provide excellent braking performance. Out back, rear brake feel is improved by reducing the rigidity of the brake hose providing a wider range of control at the pedal.
