These kits are designed for, throttle "on", clutchless up and down shifting by just pushing the buttons. Clutch use is only required for starting and stopping. Suits best on sport bikes, drag bikes and custom bikes with firm clutch lever operation. All Electric Up/Down shifter kits include a dual button handlebar control, a chrome plated shift cylinder, bolt-on shift cylinder support bracket, a state of the art control module that quickly and reliably interacts between the button control and shift cylinder, and the ignition interruption module. For your ease, installation instructions come with each kit.
