Product 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.

4.0 out of 5 stars Mixed feelings.
By Jay M on September 3, 2018
So here's the deal. It definitely helps on long rides. it allows you to stretch out your hand while still keeping pressure on the throttle. So it does allow you to ride longer and it does what it says. But it's a trade off... Where it is on your handlebar will be much thicker and hard plastic rather than soft and grippy. This is pretty hard to get use to. I've been using it for months and I'm still concious of it being there every time I ride because the hard plastic edge kind of digs into my finger... The other downside is that this thing can actually be kind of dangerous. You need to get used to it at slow speeds. Turning left at slow speeds will cause you to push down on it and rev the throttle untill you get used to riding with it. after you are use to it it's not an issue though.. the other dangerous thing is that on about 3-4 seperate occasions it has worked it's way outward to the end of the grip while I'm riding and clamped down on the bar end weight, essentially clamping the throttle in place, which is a bit unnerving and could end bad in the wrong situation.

5.0 out of 5 stars A must have for anyone who rides alot
By John on March 30, 2016
I honestly did not expect this thing to be so great but after having it on the bike for a couple weeks I don't know how I lived without it. I have two Harleys, a Vrod and a 2014 Ultra and I was initially a little hesitant about what size to get because my grips seemed to be right between the size difference between the CB2 and CB4. The Vrod is right at 1 3/8 and the Ultra is closer to 1 1/2 and I wanted one that could fit either bike. The CB4 turned out to be the perfect fit. The Vrod grips are a combination of metal and rubber so I used the rubber sleeve that was included on it and the Ultra's grips are more of a rubber texture so it wasn't needed.

It does take a little getting used to. You'll want to mess with it in the driveway before hitting the highway to make sure you have it adjusted properly. It will rotate freely when you turn it upwards (clockwise) so it can be spun around out of the way but will compress against the grip and stay in place when you press down on it. I honestly didn't think I'd need one for the Ultra since it has cruise control but the Crampbuster is nice for just riding around town as well. It definitely does relieve your grip, allowing you to turn the throttle without "squeezing" the grip. Now if only they would come up with something for my clutch hand!

Excelente producto, es muy universal porque se abre según el puño de la moto, viene con una cinta que va entre el puño y el crampbuster y le da mucho más agarre para que no resbale, se siente de calidad el producto y como mencione muy universal, fácil de poner o quitar
