Similar to the engine mapping switches that MotoGP bikes run, this handy little 7 button housing mounts to your handlebar and has 5 buttons on the front, and 2 on the rear. Allows you to run cdi mapping, re-gen control, lighting, rev limiter etc right from your handlebar. Top button on the front is persistent type, all others are press and release to toggle. Tough aluminum housing ensures long life. Requires 7/8" bar diameter at mounting point.
