This is a must have for any rider who travels, bar none! Thanks to its ingenious design, the rider can lock the throttle simply by a ¼ turn of the lever, providing nearly double the vertical action when compared to the stock star wheel. Made of aircraft grade materials, durability is a cut above the rest. The cleverly designed spring loaded spline makes fine tuning easy. For 2013, the kit contents have been revamped to simplify installation & all H-D kits include the new, easier-to-operate handle.
