The problem
ON CERTAIN MOTORCYCLES, DURING LONG PERIODS OF RIDING AT SUSTAINED HIGH ENGINE RPM, VIBRATION WITHIN THE BRAKE FLUID RESERVOIR CAN CAUSE THE BRAKE FLUID TO FOAM. THIS COULD ALLOW AIR TO ENTER THE FRONT BRAKE SYSTEM WHICH COULD LEAD TO A LOSS OF FRONT BRAKING EFFICIENCY.
Risk
AIR IN THE BRAKE SYSTEM CAN LEAD TO A LOSS OF BRAKING CAPABILITY, INCREASING THE RISK OF A CRASH.
What owners should do
DEALERS WILL BLEED THE FRONT BRAKES AND INSTALL A DAMPER WEIGHT IN THE BRAKE FLUID RESERVOIR. THIS WEIGHT WILL DAMPEN POSSIBLE VIBRATIONS THAT CAN CAUSE FOAMING OF THE BRAKE FLUID. THE RECALL BEGAN ON DECEMBER 14, 2007. OWNERS MAY CONTACT BMW AT 1-800-831-1117.
