After a short hiatus, the original CrampBuster is available in NZ once again! The CrampBuster allows you to comfortably maintain a steady throttle control on your motorcycle. The easy-to-install paddle dramatically reduces wrist fatigue often caused by long rides.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.
