2017 BMW R 1200 GS ADVENTURE

SERVICE BRAKES

It is not clear which rear brake component is failing. It seems to be either the master cylinder or the ABS control module, but nothing seems to be conclusive. The failure alters the power of, and force required to apply, the rear brakes, changing the riding characteristics of the motorcycle that could lead to serious injury or miscalculations in application of the rear brake to minimize stopping distance. Apparently the component has been inspected by the manufacturer, however there has been no concrete solution that would guarantee a permanent fix. There are no warning lamps or visual indicators to prepare riders that the rear brakes may be compromised or dysfunctional. There have been multiple incidents of this failure from new. After 7 years and over 800 posts (in this thread alone), owners and BMW dealers have not been able correct the defects with 100% certainty. [XXX] This impacts owners of this motorcycle with a Production Date Range of Sept 1, 2012 through to Aug 31, 2020. BMW knows of the problem and released a Technical Service Bulletin SIB 34 01 21 to Dealers [XXX] . INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
