The Up / Down Shift Assist allows the rider to perform clutchless up-shifts as well as down-shifts with ‘auto Blip’. This shift assist is designed as an add on module and must be installed in conjunction with a Rapid Bike Evo or Racing fuelling kits.

It connects via CAN-bus to the Rapid Bike Evo or Racing wiring harness and features a push pull load sensor with an auto-calibration system to control shifting kill time and provide a dynamic fuelling cut.

It features full compatibility with the YouTune handlebar controller for management of the pressure level required to activate shifting operations. Another additional feature managed via YouTune is the modulation of engine/throttle response sensitivity.
