Enjoy those longer rides and relax your throttle hand with the Mechanical Throttle Assist. This is the simplest and 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 and 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 shutdown when needed. Add the left side for a bar end weight matched pair and ride on in comfort.
