Enjoy those longer rides & relax your throttle hand with the Mechanical Throttle Assist. This is the simplest & cleanest looking throttle position holder available. Attaching to the end of your handlebars, this beauty looks like a bar end weight. Simply hold the throttle at desired location & roll your little finger back to hold your throttle in position. The spring loaded tensioner makes it easy to set without over tightening for easy throttle shut down when needed. Add the left side for a bar end weight matched pair & ride on in comfort. Sold each.
