High-efficiency air intake ensures optimal performance and instant throttle response, while the fast and precise close-ratio 6-speed transmission helps you shave precious seconds off your lap times.
Its sharp-looking, ultra-slim bodywork gives you a high degree of control on the ground and in the air, and the flat seat and race-grade ergonomics let you move easily around the bike under hard braking and acceleration.
