Cruise control is a common feature on automobiles, though less so in the motorcycle market. Given that continual throttle application on long rides can be a real pain in the wrist, many riders long for such a convenience. As a cheat solution, bolt-on locks that hold the throttle at a set position are available, though quality varies and generally they need to be activated by the throttle hand anyway. [Nixie] wanted a solution that would leave the right hand entirely free, and held, rather than locked, the throttle.
The device [Nixie] came up with is essentially a brake that fits inside the throttle handle and holds it in position. This is achieved with a mechanism that presses a pair of small brake shoes into the inside of the throttle, holding it from rotating back to neutral when the rider lets go. The brake is activated by a control on the left handlebar via a Bowden cable, allowing [Nixie] to activate the throttle hold on the highway and use the right hand to check pockets or simply rest.
It’s a tidy build, and [Nixie] does a great job of explaining the various design choices and the intricacies of the Bowden cable actuated mechanism. It’s anything but a one-size-fits-all build, but other enterprising machinists could certainly duplicate the design for other motorcycles without too many problems.
For those interested in more traditional cruise control, we’ve featured a teardown of a simplistic 90s Jeep system before. Video after the break.
