This handle bar mounted controller has several great features. Two control knobs allow you to change the launch rpm setting of the MC-4 manually for last second changes. This way, if you're in the staging lanes you can compensate for changing track conditions with a quick twist of a control knob.

The end of this controller also has a built in Shift Light! A cluster of super bright red LED's will illuminate when the engine rpm reaches the programmed level to alert you to shift at the precise time. There is also a row of bright green lights that will illuminate in sequence to show you which gear the MC-4 presently in.
