Quickshifter+ allows upshifts and downshifts to be performed without the need to pull the clutch lever. The main benefits include shorter shift times and a more precise and smoother ride. The load reversal impact on the rear wheel is noticeably reduced, traction is improved and the rider can keep full grip on the handlebar. The Quickshifter+ uses two sensors: one on the gear shift lever that detects movement on the shift rod when the rider upshifts, so the system cuts the ignition instantaneously. A second sensor detects the gear engagement, reapplies the injection and opens the butterfly valve. When downshifting, the system matches the engine speed to the speed of the lower gear. If desired, the system can also be switched off.
