My 2009 Speedmaster has a BrakeAway Cruise Control. It was on the bike when I bought it 2 years ago with 6k miles on it, and I'm sitting on 12.5K miles now.
The BrakeAway is pretty slick. It gets the job done, allowing me to take my right hand off the grip if I need or want to.
Sometimes, it will hold set speed fairly well. Most times, though, it allows the throttle to creep, and it may creep up or down. It's usually a slow enough creep that I'm able to do what I intend to do with my hand off the grip, but 9 times out of 10, it is not going to hold set speed for very long.
Am I glad I have it? YES!!!
Am I going to take it off the bike? NO!!
I was always curious about the Throttlemeister, but never felt it was something I just had to have. Indeed, with well over 100K miles on my 2004 Speedmaster without any kind of cruise control, and I wouldn't necessarily choose to ride the 2009 anywhere just because it has CC. I try to split time between them as equally and fairly as I can, alternating rides between the two regardless of where I'm heading.
It may have some way of fine-tuning it, but I haven't researched it, or even looked hard enough at it to find out. I wouldn't ever intend to leave it set for very long anyway.
Not sure if it matters, but my 2009 does have Kuryakin IsoGrips, so maybe, if the BrakeAway is model-specific, it might work better with stock grips. I'm just thinking out loud...
For what it's worth, though, as far as the grips go, I'm pretty partial to the stock grips on my '04. After all the miles they've carried me, with no complaints on my end...
I have a buzz in the 2009 I haven't figured out yet. Highway speeds, it will flat numb my hands. Changed both tire's with no effect on the buzz. Will change chain and sprockets soon. Currently running 16t front, but the buzz was there with the 17t it came with. I'm going to an 18t to see how that does. The chain looks good yet, and other than the tire swap 2 years ago, I have not had to adjust the chain since.
