The CrampBuster provides a way for comfortable throttle control, and dramatically reduces the wrist fatigue often caused by long rides. The CrampBuster will rotate forward all day long. Yet when downward pressure is applied by your hand, the throttle is regulated effortlessly and accurately without squeezing. RyKel’s Acrylic compound cruise control fits on the throttle grip. No tools are required for installation. Just spring it open, and slip it on. The CrampBuster - the “original” and affordable motorcycle cruise control!

NOTE: Use 6258 and 6254 on grips with 1-7/16" to 1-3/4" outside diameter. Use 6259 and 6257 on grips with 1-1/8" to 1-3/8" outside diameter.
