NHTSA Complaint #10474049 — 1999 BMW K1200LT

THIS IS SAME FAILURE AS DESCRIBED IN ODI NO. 10439549, AND CURRENTLY BEING INVESTIGATED UNDER CAMPAIGN DP12001. MY 1999 K1200LT HAS HAD THE FINAL DRIVE REBUILT TWICE AND REPLACED TOTALLY ONCE AT BMW DEALERSHIPS. THE FIRST TIME WAS A REBUILD ON 9/25/2004 AT 37290 MILES AFTER THE FINAL DRIVE STARTED GRINDING. THE NEXT WAS 9/12/07 AT 54929 MILES WITH THE SAME CIRCUMSTANCES. THE MOST RECENT WAS 8/28/2012 AT 73001 MILES AFTER THE FINAL DRIVE FAILED COMPLETELY, LEAKING DRIVE LUBRICATION ALL OVER THE REAR WHEEL AND DISK BRAKE. REAR BRAKES SUBSEQUENTLY FAILED AS WELL. THIS HAPPENED AT INTERSTATE SPEEDS OF 75MPH. COSTS FOR REBUILDS RUN $400-600 AND THE LAST REPAIR/ REPLACEMENT OF FINAL DRIVE AND BRAKES WAS $2023.00. MY EXPERIENCE INDICATES THAT THE DRIVES ONLY LAST 20-30,000 MILES. I BOUGHT THE BIKE WITH 11,000 MILES ON IT AND I DO NOT KNOW IF THE FINAL DRIVE HAD BEEN REPLACED PRIOR TO MY PURCHASE. THESE FAILURES HAVE ALL BEEN ATTRIBUTED TO THE FAULTY ASSEMBLY OF THE FINAL DRIVES, WHICH REQUIRE A VERY CAREFUL MEASUREMENT OF A TAPERED WHEEL BEARING PRELOAD. MOST REBUILDS BLAME THE FAILURE ON TOO MUCH PRELOAD. NEWER DESIGNS BY BMW HAVE REPLACED THE TAPERED BEARING WITH A BETTER DESIGN THAT DOES NOT REQUIRE THE EXACTING STANDARDS FOR PRELOAD. FAILURES ON THESE UNITS HAVE BEEN DRASTICALLY REDUCED. *TR
