Crampbusters

The Crampbuster allows you to comfortably maintain a steady throttle control on your motorcycle. It eliminates the need to clench your wrist for long periods of time and makes riding much more enjoyable.
The Crampbuster is not a throttle lock, but rather a motorcycle cruise assist. With a relaxed hand on the throttle, this type of cruise control allows for much easier throttle operation. A Crampbuster is easier to operate and more versatile than traditional and mechanical motorcycle cruise controls.

No tools required! Just spring it open and slip it on.
