Can be used on standard and custom grips on bikes with 7/8" and 1" handlebars.
NOTE: Also Works on Motorcycles with oversized 1 1/2" Handlebars as well because they use grips for 1" handlebars.

The CrampBuster provides a way for comfortable throttle control, and dramatically reduces the wrist fatigue often caused by long rides.

RyKel's Acrylic compound cruise control fits on the throttle grip. No tools are required for installation. Just spring it open, and slip it on. The CrampBuster will rotate forward all day long. Yet when downward pressure is applied by your hand, the throttle is regulated effortlessly and accurately without squeezing. The pressure of the heel of your hand causes CrampBuster to tighten and maintain it's tight hold. You can also put it on the left grip.

Benefits:

• Full throttle control with a relaxed hand
  
• Reduces hand fatigue and cramping Comfortably fits your hand
  
• Easier throttle operation
  
• Eliminates throttle "creep"
  
• Doesn't lock throttle on

The CrampBuster is simple and inexpensive and a biker's best friend. (OK... It ranks among a biker's best friends.) It's guaranteed- if it breaks Crampbuster will replace it.
