This feature lets you shift up or down more quickly and easily without the need to operate the clutch or throttle. When activated, Quick Shift automatically interrupts power delivery just long enough to produce smoother, almost uninterrupted acceleration when you shift up. When decelerating, the system automatically opens the throttle valves just enough to increase rpm and match engine speed to the next-lower gear ratio. The result of this hands-free automatic blipping function combines seamlessly with engine braking to create a highly satisfying experience when downshifting. Bi-directional Quick Shift works in unison with SDMS to bring you even greater riding fun with a more linear feel.
