CrampBuster Motorcycle Throttle Control

The CrampBuster Throttle Control is the original cruise-assist accessory, and thousands of riders worldwide enjoy this easy-to-use tool.

There are no moving parts or tools required. It works much like an oil-filter wrench; simply stretch it open and snap it on the outside of your grip. It will rotate freely clockwise (upward), but when turned counterclockwise (downward) by the weight of your palm, it pinches and the throttle is pulled open.

CrampBuster is the original design, not a copy or an imitation. When you buy a genuine CrampBuster, you know you're getting the real deal.

Works well, but...
The Throttle Boss works as advertised, but keep in mind that when set for highway cruising, it may interfere while at lower city street speeds. I found the first week or so that I would be accidently reving the engine while braking. Just keep adjusting it until it's in the sweet spot where you can use it at speed and not interfere with braking.

Best low-cost addition to any bike.
Do you have a problem with your throttle hand getting pins and needles or cramps? What about a tired or sore writst? Many people have a problem with their glove pinching the meaty part of the hand near the fingers.____This can solve all of these!

It allows you to stretch your hand without the problems with mechanical throttle holders. I had Kuryaken grips with their integral throttle fin and it hurt my hand because it was so small and at the end. This is better. Beware of sizing. Got one for an adventure bike and a cruiser, but both needed the larger size.

PROS: Good Cost, Hand and wrist relief, Simple construction

Worth twice the price
I borrowed my wife's Cramp buster yesterday , rode A total of 381 miles . When I was on the twisties with my buddy I turned it so it was not in the way , back on the straight Texas highway flip it around . I could maintain speed with my hand completely open .

Required for those long hauls!
I have been using the Crampbuster for over a year and it still works. When I was living in Florida, I rode back and forth from Tampa to Jacksonville and the Crampbuster delivered. Now I ride back and forth from Maryland to Norfolk, VA which is around four hours one way for me and the Crampbuster still delivered. I put the Crampbuster at the end of my grip and just lay my palm on it. When I get to a light or in traffic, I just move my hand up the grip and off the Crampbuster. Only issue is adjusting to increase speed. For safety, don't adjust it while at highway speeds. Pull over, move it up or down then get back on the road. Overall, this is your best bet, especially for people who are afraid of the cruise controls that lock down your grips.

PROS: Easy Installation, Good Durability, Prevents grip fatigue

CONS: Can't adjust on the fly

Immediate relief from my throttle hand cramping. This allows you to vary the position of your hand/grip on the throttle. Quick learning curve so I now leave it on the bike all the time, even in town. 2007 FJR.

Don't ride without one
On my very first long distance trip, I picked one of these up at a dealership we stopped at. I noticed an immidiate difference, and I'll never ride without one again. This is the best money you will ever spend on your motorcycle.
