I HAVE NEVER CRASHED MY 1999 BMW R1100SA MOTORCYCLE AND MAINTAINED IT STRICTLY BY BMW SUGGESTED SCHEDULE. 64K MILES ON THE ODO NOW. THOUGH BIKE HAS NOT LEFT ME STRANDED, IT HAS HAD ENDLESS PROBLEMS - BIG PROBLEMS AND BEEN OUT-OF-SERVICE FOR REPAIR IN EXCESS OF 85 DAYS IN 2 YEARS. IT HAD A BREAK IN THE FRAME (I COULD NOT HAVE BROKEN THE FRAME!); THE CATALYTIC CONVERTER FAILED AND THE NEW ONE DOES NOT FIT CORRECTLY AND IS BREAKING THROUGH A FRAME BRACE, PERHAPS BECAUSE OF ANOTHER FRAME PROBLEM (PRESENTING SAFETY ISSUE); THE ENGINE HAS BEEN REBUILT TWICE ~ OVER HEATING, IMPROPERLY CUT VALVES AND PITTING CYLINDERS, EXCESSIVE COMPRESSION BLOW-BY; 3 SETS OF REPLACED HEADER PIPES DUE TO PITTING FROM EXCESSIVE HEAT; 4 SETS OF FAILED THROTTLE/CHOKE CABLES - CABLES SHREDDED AT JUNCTURE BOX; TWICE REPLACED REAR WHEEL BEARINGS; REPLACED CLUTCH AND TRANS. DUE TO FLOODING W/OIL BECAUSE OF FAILED REAR ENGINE SEAL THE BMW APPROVED DEALER IGNORED; EXCESSIVE OIL CONSUMPTION STILL; BOTH THROTTLE BODY COMPONENTS HAVE FAILED AND BEEN REPLACED; THE ENGINE TEMP SENSOR FAILED AND WAS REPLACED. BMW'S WARRANTEE FIXED MOST FAILURES HOWEVER THE LIST IS ENDLESS AND NOT IN LINE WITH A HIGH PERFORMANCE MACHINE. BMW DECLINES TO ADDRESS SAFETY CONCERNS THAT COULD BE A RESULT OF FRAME/STRUCTURAL PROBLEMS AND INSTEAD IMPLIES THAT FAILURES ARE FROM HIGH MILEAGE OR USER.
