huh?
Not sure what you mean there. There is no 'standard' reverse button
but if you are talking about the red button on the throttle (generally for lighting) then it should work, but remember the 'Cruise' signal is momentary, having said this if you push the lighting switch gently enough it will be momentary
I'd scrap the idea if you are thinking of having reverse on your lowrider bike, unless its on a trike reverse is probably more trouble than its worth
