Cruizin' For a Bruizin'
Be very careful, adapting a car cruise control into a Burgy.
The way a cruise control regulates changes in speed/throttle is through the speedometer. If you get an AN650 service manual, you'll notice the (speedo) tach timing inputted into a digital module, at the wiring diagram.
Since the Burgy is mostly digital (through a series of nearly 16 sensors) ,the adaptation would be quite interesting. Paralleling the cruise control's speedo sensing onto the Burgy's circuit could distort the signal that the Burgy is depending on and could produce inaccurate speedometer/odometer readings and advanced wear on the speed sensor. Will your cruise control go to full throttle if the speed sensor ever opens up?
Before I would lay out money for a car cruise control to fit onto my Burgy, I would check out the travel limits of the cruise control servo motors. A small change in throttle position on the Burgy may be quite different for a car. Abrupt and uncontrollable changes in automatic throttle travel, by adapting an incompatible car cruise control into your machine, could make you regret the entire affair altogether.
I would especially be concerned first and foremost with the disengagement system compatibility with not only the Burgy's linkage/pivot dimensions but with my own physical limits of safe and redundant manual control.
From the many road trips I’ve been on, I’ve noticed that there is no such thing as flat road.
I use a simple small plastic palm-rest wedged over the throttle grip to alleviate long-term stress on my right hand. The Burgys ‘D’ transmission mode, while riding gentle grades, tends to adjust torque and resulting constant speed for you, up to a limit, depending on the speed you’re cruising at. The Burgman 650 is not your fathers Suzuki and you will not have the same comparatively gross throttle grip changes while cruising rolling hill interstate highways.
