I did a side-side comparo on bmwmotorcycles.com just because I didn't know what else was different on the 800. Besides the accessories and front fork, all specs where the same, so why does the 650 have 14 less hp? Same engine right?
The 650 twin has only one front rotor and the 800 has two, so while you might be able to mount the wheel, you would have to figure out the brake situation. I'm sure a wheel builder could make a 19 inch wheel with the stock 800GS hub, rotors and abs stuff. Won't be cheap, though...
