@BigNorm several of us have installed
McCruise by an aerospace engineer (worked on the Australian F-111s in the day) who has adapted OEM cruise control for automobiles, to motorcycles. And properly installed, it works every bit as well as any cruise control you've ever had on a car. The instructions are truly complete (even better than the Haynes manuals of old), and if you still have questions, you can ask us, and ask him.
It's a pretty penny, and worth it.
There are far far less expensive options, that require more attention by the rider -- as always, value is in the seat/wallet of the rider.
