Just looking for some feedback and opinions. The ring bearing on my '02 K1200RS finally died. I know this bearings wears out (I've heard that it should be replaced at about 40-50K?) and the wear starts from day 1. This bearing wore out at about 71k. As luck would have it, I was near a very reputable BMW dealer, who cleared their schedule and got me back on the road in an afternoon.
My question is that I had the major service for the bike done at about 70K (This was done at a different BMW dealer) , to include new oil in the final drive. Shouldn't the technician have noted metal shavings and bits when the oil was changed? Or can the bearing wear this much in about 1,000 miles?
