CrampBuster CB4 Black for Oversize Grips.
CB4 fits grips 1-3/8" (35mm) or larger diameter
Cruise Assist provides a way for comfortable motorcycle throttle control and dramatically reduces wrist fatigue often caused by long rides. It is not a cruise throttle lock, but rather a cruise assist. No tools are required for installation. Just spring it open and slip it on.
Downward pressure causes the CrampBuster to tighten and increase hold on your throttle grip. Upward pressure release the CrampBuster and allows for positioning adjustment.
All CrampBusters are made from a durable and virtually unbreakable plastic, not metal.
