There's another post on the site that discusses CC.
I came to the conclusion during that discussion that there are large differences between a conventional bikes' CC needs and the Burgmans' that are so great that the Burgman triumphs just the way it is.
Take a Kawasaki Vulcan out on an interstate trip and note the throttle adjustments required, then the Burgman. The Burgman transmission tends to self-adjust for torque requirements unlike a 5-speed conventional. At highway speeds a major factor in speed control is torque. Take a conventional 5-speed up to 80mph and the throttle requires less adjustment. Get off of the highway and cruise on a frontage road at 40mph and the throttle adjustments become quite large averaged over time.
For the most part, unless changing speeds with throttle, it takes very little throttle movement on the Burgman AN650 to stay at the same speed.
I use one of those aftermarket grip paddles that takes the stress out of holding the throttle while making small adjustments too, at cruise speeds.
I've considered also using a throttle tensioner - the kind that has a C channel that slips into the cable fitting below the grip. If the tensioners plastic channel were made wider and a spring were attached to it and to the fitting, small increases of throttle would have greater latitude. Then, relaxing the tensioned throttle grip would allow the C channel to once again rest against the Set low side until the tensioner is disengaged (arm up).
Lately, I've met some mechanics that are against using a throttle tensioner over safety concerns that a bike would stay running during and after an accident, but the Burgman has a Tip Over switch that cuts the engine if laid down. I've been using tensioners since 1980. I glue the provided hex wrench into the tensioning adjustment head to give me the best setting in all situations.
When adjusted too tightly, a throttle tensioner takes excessive pressure do adjust throttle (wrist pain) and it can rub against grip plastic when disengaged, thus delaying time until full idle. Adjusted too loosely and it will disengage with engine vibration or small bumps.
I prefer to keep my Cruise Controls manual because I don't want to be accelerating up some hills where I can't always see. And don't forget, the majority of other vehicles don't have CC and are slowing down on the same hills. Sometimes it's best to stay in synch with traffic rather than establish computer controlled speeds that have no eyes.
In conclusion, given the special CVT attributes of a Burgman transmission, there may be no presently available off-the-shelf black box CC solutions that could otherwise make you a risk taking test pilot.
