I have not done the install but have done some extensive research on the subject. Here are my conclusions:
The McCruise gets great reviews and just about everyone has reported that it works just like a factory electronic cruise control. If I bought the kit I'm confident I could do the installation myself.
The install is not for a novice. Whoever does the install should be familiar with removing the body panels, have prior experience working on motorcycles, be good at following directions, troubleshooting and electrical wiring...access to a wiring schematic might be handy as well.
From what I have read, the instructions are very well written and if you can follow directions and not skip around it is do-able. I'm confident in my abilities when it comes to mechanical things and I think I could do it. If you lack experience working on motorcycles then you should hire it out.
I still can't understand why no one has just bought the parts from Honda and installed these on an older bike? These bikes aren't all that different I wouldn't think unless there is some special mechanical linkage or ECU issues of compatibility??
I purchased McCruise for my F6B '13. Had the Honda dealership do install. I have mechanical ability but decided against doing install myself, just a personal preference. As to the function and reliability, no complaints! I've had it for 2 years and it has always performed perfectly. As to retrofitting a honda cruise, I was told that it was incompatible without major overhaul...? Don't know for sure, it's just what I was told. Good Luck
