I'VE OWNED THIS BIKE SINCE 2002 AND SILL HAVE IT. DURING THAT TIME I HAVE EXPERIENCE TWO REAR DRIVE FAILURES AS DESCRIBED IN ODI NO. 10439549, AND CURRENTLY BEING INVESTIGATED UNDER CAMPAIGN DP12001. AT THE TIME BMW WAS IN DENIAL ABOUT THE ISSUE OR CLAIMED THAT IT WAS RARE. WELL, I KNOW 6 PEOPLE WITH THIS SAME MOTORCYCLE AND WE'VE ALL HAD THE REAR DRIVE FAIL. I AM THE ONLY ONE TO HAVE IT FAIL TWICE. I BELIEVE BMW HAS SUPERSEDED THAT LARGE BEARING IN THE REAR DRIVE WITH A NEW PART NUMBER AND IT'S HOLDING UP BETTER. ANYWAY, THE FROST TIME MY REAR DRIVE FAILED THE BEARING HAD "PAULED" AND AS IT CAUSED [XXX] DRAG THE CAGE AROUND THE BALL BEARINGS CAME APART AND TOOK OUT THE SEAL. ONCE RELIEVED OF IT'S OIL IT'S NOT LONG BEFORE THE BEARING FAILS. THE REAR LOCKED AND I CAME TO A STOP MORE RAPIDLY THAN I WOULD HAVE LIKED. I DROPPED THE BIKE TO THE RIGHT AND DID A LITTLE BODY DAMAGE TO THE UNDERCARRIAGE AND SADDLE BAGS. I WAS OK BUT STRANDED WEST OF FRISCO COLORADO. I WAITED MOST OF THE NIGHT FOR A TOW TRUCK TO COME UP FROM DENVER. I SLEPT ON THE SIDEWALK OF THE BMW DEALER THAT NIGHT AND HAD TO RENT A CAR AND "CAMP" WHILE WAITING FOR REPAIRS. MISSED MOST OF A WEEK OF WORK TOO. ANYWAY, THE SECOND FAILURE I CAUGHT EARLIER AND BOUGHT THE PARTS AND ASSISTED ION THE REPAIR SO IT COST MAYBE $600 COMPARE TO THE BMW REPAIR OF $1700. IN TOTAL THAT AND $100 RENTAL AND $50 CAMPING AND WHO KNOWS WHAT A WEEK OF WORTH COST ME. *TR
