Final drive failure causing oil to spill onto rear tire while riding. This is the same failure as described in odi no. 10439549, and currently being investigated under campaign dp12001.
Crown gear bearing failure, no oil leak. Progressive vibration felt in footpegs and seat, several very brief rear wheel lock-ups. Metal fuzz on magnetic plug, pulled the drive, sent to an independent expert (not a bmw dealer) who confirmed the failure and rebuilt the drive.
Abs brake assist servos (power brakes) intermittently fail to operate, causing unexpected loss of braking power, once assist servo power is lost the residual braking is approximately 20% of assisted braking, this causes heart stoppage while trying to not crash and/or hit other traffic.....very unsafe when this…
