Don't know what mine is called. Got it at a moto show. It has a rubber slip on ring about a half inch wide that you slide all the way down on the grip. Then you put a this plastic 'arm' over it and it grips. You merely push it down to your desired throttle opening and it holds it there. Close throttle all the way and it goes back to no effect. It works great and was a 12bucks I think. I will look when iget home to see if it has a name. Will work on any bike.
