Bi-Directional Quick Shifter
Enables clutchless upshifts for instantaneous acceleration on straightaways and track apexes.
Traction Control System
Advanced electronic system that minimizes rear wheel slippage during intense throttle application on slippery or high-lean surfaces.
Bluetooth Y-Connect Telemetry
Pairs with your smartphone to provide real-time fuel consumption, maintenance notifications, last parking location, and rev telemetry.
