                                                                                                          The First Universal Motorcycle Cruise Assist

The original Crampbuster started life as a universal assist. It was originally designed 1 1/8″ in diameter with the “paddle” portion protruding back toward the rider about 2″ long.  In 1991, the editor of “Popular Science” magazine secretly purchased a Crampbuster for testing. He was so impressed with its performance that the Crampbuster was featured in the “What’s New?” section of the May 1991 Popular Science issue! As endorsements are considered, that was the equivalent to being on the “Johnny Carson Show.” It was then that people began to take the Crampbuster seriously!


Modifications: No Longer a Universal Motorcycle Cruise Assist

When Harley introduced their oversized grips a few years ago, some people complained of having to work too hard to stretch the Standard Crampbuster open enough to install it. So in an effort to keep their customers happy, Crampbuster responded with an Oversized model. This new addition to the Crampbuster family had an increased diameter of 1 3/8″ in diameter to facilitate easier installation on to the ‘oversize’ grips. Now the idea of a “one size fits all” motorcycle grip control was replaced with the thought of having not one universal motorcycle cruise assist, but two different Crampbuster models.



The next modification came when the folks at Crampbuster noticed some pretty interesting (to say the least) looking Crampbusters out there in use due to “self modifications.” While most folks liked the Crampbuster just the way it was. They used everything from a hacksaw to an ax to modify their  Crampbuster.  It was then decided that a more “professional” looking shorter model should be made available. So in early 2005 the new Standard Wide CB2 model was introduced as the third member of the Crampbuster family.


It didn’t take long for Harley riders to begin clamoring for a ‘Wide’ model for their ‘fat’ grips too, and so the “Oversize Wide” model was born, creating the ideal Harley motorcycle cruise assist.  The CB3 and CB4 model will fit the oversize grips.    CB4
