2003 1150RT with 99,300k. Bought this bike new and we've been to some amazing places, but maybe it's time to part ways. Two years ago the dealer replaced the rear main seal on the engine, and a seal on the final drive, to the tune of almost two grand. Now I have massive metal fragments showing up on the final drive magnet. Dealer says some kind of bearing may have gone, and estimates a $1500 repair. I have always changed my own fluids yearly, and switched to Amsoil synthetic GL5 about five years ago, a highly rated oil. Is this normal to lose the final drive after just 99k? My Dad had a Mercedes with 550k miles when he sold it,on the original rear differential. This may be the final straw for this bike, thinking of selling and reevaluating brand loyalty.
