Just found out My 07 RT with 31000 miles needs the final drive rebuilt. After new tires, I noticed a vibration in the bike that was not there before, mostly feeling it in the foot pegs.
I had just gone a couple of miles from home when I could smell burning brakes. I pulled over and found the rear brake and caliper too hot to touch. Thinking my rear brake was locking up, I put the bike on the center stand and put in it gear. The rear wheel wobbled about an 1/8th.
I called the Dealer and they said the final drive was out. No oil leaking from FD and all periodic service was done. The good news is that BMW will pick up most of the tab.
