2008 R1200RT - 32,000 Miles - Final Drive Failure
Here's another one to add to the list. My RT was in for a 6K service at my BMW dealer. During the service the technician discovered that the final drive was grinding. Looks like a replacement is the next event. The folks at the dealer advised me not to ride it so I had an ignominious ride home on a beautiful day in a rental car.
I had purchased an extended warranty a couple of years ago, and so the Service Mgr. is working with that company to get authorization to replace the unit. I think I'll be OK, money-wise. FWIW, this RT had been serviced strictly by BMW dealers since new.
Resolution of Final Drive Failure
I heard from the Service Manager of the BMW dealership which is working on my RT. He said that BMW is sending an entirely new final drive unit from Germany to replace the FD in my RT, thus this is a replacement not a rebuild of the unit. As my extended warranty will cover that cost, I'll have no out-of-pocket expenses (other than the cost of the warranty) and will get two years of BMW service/parts warranty on the replacement unit. I think that since they're replacing and not rebuilding the unit, and as a result, won't be disassembling it, we may never know which parts inside actually failed.
Actual Cost of Final Drive Replacement
I picked up the bike two days ago (I had been away for two weeks out of the country). For those who are interested in the specifics, all the parts came to $1951.60, and labor came to: $150.40. Anyway, the big piece was a 33 11 7 726 895 part for $1857.68. This is described as a "Right-angle gearbox with vent, silver." Another $92 covered nuts, pivot pins, screws, etc. Since this install was done at a BMW dealer, it now has a 2-year warranty from BMW. Since it's a brand-new final drive, I was advised to return to the dealer to change the fluid at 600 miles on the new piece.
For me, the cost of the extended warranty was worth the peace of mind as I embarked on an 8200-mile trip to CA and back last Fall. Now that it has actually paid off, I'm pleased that I spent the $$ but am a little nervous about the future with this RT.
