The MPS Quick Shifter gives you perfect shifts at full throttle by just pulling the shifter. You still manually shift with your foot but you won't need to let off the throttle or pull in the clutch to perform lightning fast up shifts. You set up the switch to activate the Sport Bike Electronic Engine Kill just as there is a load on the shifter. The kill unloads the trans allowing the shift just like an air shifter. The Quick Shifter includes all components and instructions necessary for a basic installation, however you will need to fabricate your own switch bracketry. The Electronic Engine Kill features easy kill time adjustment.
