The Domino Black Throttle Tube turns further around the handlebar than stock throttles to provide a slower, softer and smoother power. Having more room between idle and wide open is great for lower level riders to build confidence and learn proper throttle control. It can also be used as a tool to minimize wheel spin in slippery conditions. Fits most modern trials bikes! Get the advantage at your next event with the Domino Black Throttle Tube!
