The percentage of motorcycles estimated to actually contain the problem is unknown at this time. The problem involves the front brake lines. Due to the current routing of the front bral<e lines, it is possible that during riding, and therefore associated Vibration, the brake lines could be under strain. If the vibration/strain is significant, the brake lines could split and start to develop a leak. If the leak became Significant, brake fluid could escape. If this happened, the level of fluid in the reservoir of the front brake system could drop. If this goes unnoticed, and the brake fluid reservoir runs empty. the front brakes could fail. However, the rear brakes are available and are capable of slowing and stopping the motorcycle. A similar issue was reported in 2008 and assigned "08V-2S4" by NHTSA. At that time, our remedy was thought to have fully corrected the problem. However, over the course of time, some non-US field reports were received indicating that the remedy was not sufficient in some cases. Accordingly, analyses were conducted in order to determine the specific problem and develop a further improvement. Please note that we first reported this new decision to NHTSA on May 21, 2010 as an amendment to 08V-2S4 but, upon discussion with the agency, it became clear that a new/separate Part 573 report was more appropriate. BMW has not received any reports, and is otherwise not aware, of any accidents or injuries as a result of this prob lem.

Not applicable. BMW will conduct a recall campaign to remedy the affected motorcycles. New brake lines, containing a "sleeve" along a portion of the lines, will be installed on all affected motorcycles. BMW expects to begin and complete dealer notification in June 2010 and customer notification in July 2010.
