I have a Rostra electronic cruise control unit sitting in my garage that I plan on installing in my GT. I have almost another year to wait until the warranty runs out before I plan to put it on. It shouldn't be particularly difficult to install the main thing is finding the necessary inputs to the cruise control. With ABS equipped bikes one can usually tap one of the wheel speed sensors for the speed input. You can't use an input directly from the engine because of the variable belt drive. That works with a manual transmission bike but not with a CVT that constantly varies the gear ratio. I put an electronic cruise on an old Goldwing a few years ago and it worked nicely. I'm hoping I can repeat it with my GT. The full electronic units are easier and more compact to use than those that operate with a vacuum source.
