The original motorcycle cruise assist
Why Crampbuster?
Easier throttle operation. A more relaxed grip. Crampbuster gives your palm a simple way to help operate the throttle.
Simple support for your throttle hand.
Comfort, simply
Less squeezing. More comfort.
A small addition to help make throttle operation easier.
Relax your grip
Use the heel of your hand to help operate the throttle with less constant squeezing. Crampbuster is designed to help reduce hand fatigue from gripping.
Support your palm
Choose a narrow or wide paddle and a grip size that suits your motorcycle. The paddle gives your hand a comfortable place to apply pressure.
Keep it simple
There are no moving parts, and installation requires no tools. A straightforward design makes the assist easy to fit and use.
Questions & answers
How does it work?
The Crampbuster fits around your throttle grip. Pressure from the heel of your hand helps turn the throttle, so you can operate it with a more relaxed grip.
Follow the instructions supplied with your product. Install and adjust its position while safely parked, before riding.
Is it a throttle lock?
Crampbuster is a cruise assist, not a throttle lock or automatic speed control. You remain responsible for operating the throttle and controlling your speed.
Why choose the original?
Crampbuster is the original design. Buying a Crampbuster supports the inventor behind this simple motorcycle grip assist.

Riders’ experiences
What our customers say.
Five riders share their experiences with Crampbuster.
Have used these every since I had a mini stroke which affected my right arm. Neurologists was amazed that I could ride after the stroke, and I told him this was my therapy. I ride everyday and the Crampbuster has assured me of it.

It must be the Midol for the hand. I tried numerous products for cruise control on my Vulcan 900, but it wasn’t until I tried your product that I found something that required less energy to use. It is truly an effortless cruise control! …I would have paid double for it…. You make a GREAT product, hope you have much success!
— Mike
Wow! Thank you for the prompt delivery and processing of my order. This simple device is everything you promised it would be…..Amazing and amazingly simple. You’ve probably saved me hundreds of dollars now that I won’t need to seek a more complicated and expensive speed control solution.

Your product is the best accessory, under $100.00, I have added to any of my bikes. I am even considering putting one on my FLH, which has cruise control, to ease the grip while holding the front brake on hills etc… My wife loves it. Thank you for a great product.

Just a note of appreciation for your product. I was almost to the point of giving up long distance rides on my Harley-Davidson Sportster due to the cramping of my throttle hand after short period of time. It got to the point where I felt it was dangerous and was not sure I could brake in a hurry if need be. I tried modifying my handlebars, using various gloves and … installing vibranators which helped some but not enough. I ordered your crampbuster and it made a world of difference. It is the single most improvement I have made to make my riding experience enjoyable again and it was very cost effective. Thank You!
