The Crampbuster provides a way for comfortable throttle control, and dramatically reduces the wrist fatigue often caused by long rides. It doesnt 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.
I like the Crampbuster, but it could use a better mounting option. It took me a few tries to get it secured just right, but once I did, it worked great. The black color blends well, though!

Nice addition for road trips
Used this throttle assist on a recent road trip, and it definitely helped reduce hand fatigue. The black color looks sleek, and it was a breeze to mount. Just wish it had a little more adjustability for different grips.

Perfect for cruising!
I just got back from a long ride using the Crampbuster CB4, and I'm really happy with how it performed. It made it so much easier to throttle without cramping up. Easy to install, and the black finish is spot on for my bike!

Great help for long rides!
The Crampbuster CB4 is a lifesaver for my motorcycle trips. I love how easy it is to use, and it's really comfortable. My only issue was the shipping took a bit long, but it was worth the wait!

Disappointed with the fit
I really wanted to love this throttle assist, but it didn't fit my bike as well as I hoped. The concept is good, but it felt a bit loose. I might look for a different model next time.
