## Overview

The Crampbuster CB4 is a universally fitting, tool-free throttle assist designed to reduce wrist fatigue and improve comfort on long motorcycle rides. Made in the USA with durable, no-moving-parts construction, it offers ergonomic palm support and precise throttle control, making it a must-have for riders seeking pain relief and enhanced riding endurance.

## Description

The Crampbuster provides a way for comfortable throttle control, and dramatically reduces the wrist fatigue often caused by long rides. It doesn't lock the throttle on and installs with no tools, just slide it on, it rotates forward with ease yet when downward pressure is applied by your hand, the throttle is regulated effortlessly without squeezing. There are no moving parts or tools required. It works on the principle of an oil filter wrench. Simply stretch it open and snap it on the outside of your grip. It will rotate clockwise (upward for adjustment) but when turned counter clockwise (downward) by the weight of your palm it pinches and the throttle is pulled open. To accelerate, simply lift it a little (causing it to rotate up clockwise) then rest your palm back on it. To decelerate, simply spin it up clockwise completely around until it comes up into a position a little lower than before. It can also be used as a rest for you left hand. Oversized version fits grips 1-3/8 inches and larger in diameter and has shorter and wider palm rest.

Review: Useful but be careful. - I fitted the Crampbuster CB4 to my Kawasaki VN1600 as I have arthritis and carpal tunnel in both hands. It is easy to fit and works well. I has certainly reduced the amount of grip I apply to the throttle and reduced pain in my joints. One word of warning, on my third ride with it on I needed to quickly reach for my brake and caught it with my wrist. This caused the engine to rev unexpectedly as I encountered a hazard. I am finding the Crampbuster to be useful but remember you have it on the bike at all times.

*by N***. on 10 September 2025*

Hatte schon mal vor 10 Jahren einen 'Crampbuster' als manuellen Tempomat und nutze diesen nun wieder auf meiner Vespa. Da dieser mit einer Kombination aus Reibung/Klemmung am Griff und den Handdruck funktioniert, muss man sich zwar daran gewöhnen, dann funktioniert es aber super und man kann elegant und exakt die Gasöffnung halten. So machen lange Fahrten mit dem Roller noch mehr Spaß
