Example, the Cruise Mate, a lever operated throttle/cruise assist invented by Thomas Lane in his garage a few years ago. Some manufacturers like Big Dog Motorcycles have adopted it as stock equipment (on their Bull Dog Bagger model) and Kuryakyn will also distribute it in its 2011 catalog.
First, let me mention that Cruise-Mate is not a cruise control device: it doesn’t release when applying the brakes and needs to be turned on and off manually. But you will still be able to turn the throttle when the Cruise-Mate in engaged (turned on) What about those Harley-davidson bikes equipped with a factory lock? Thomas Lane explains The original star wheel provided by Harley-Davidson is very small and tucked under control making it very difficult to access. The original equipment star wheel also utilizes a very fine pitch thread, which takes several turns of the star to engage or disengage the throttle lock feature. Cruise-Mate is engaging and disengaging twice as fast as the original star wheel device. Cruise-Mate also incorporates an infinitely adjustable lever style handle for easy access by the thumb of the operator. Cruise-Mate will typically apply sufficient pressure to hold the throttle in place with 1/4 turn or less of the handle. Sold with complete installation and operating instructions including pictures every step of the way. Info at: 508-789-0862. Cruise-Mate
