The National Highway Traffic Safety Administration has officially announced the recall of 43,426 BMW motorcycles for a problem with the rear wheel mounting flange.

  • 2007 BMW R1200S (477 units)
  • 2005-2007 BMW R1200ST (555 units)

As previously announced, the rear wheel mounting flange may crack if the mounting bolts are attached with too much torque. This may cause the rear wheel to loosen, potentially causing a loss of stability and increasing the risk of a crash.

According to documents released by NHTSA, BMW first became aware of the problem on Aug. 6, 2014, after receiving a report of an accident in Spain involving a 2004 R1200RT. The manufacturer began in analysis of the affected motorcycle and concluded the rear wheel had separated from the flange. BMW continued to analyze the crashed bike and found no other issues except for cracks at the rear wheel flange’s threaded bolt holes.

In January 2015, BMW began inspecting 58 customer motorcycles around Munich, Germany with between 2,500 and 40,000 miles on them. Three of the inspected bikes had cracking rear wheel flanges that needed replacement. Those three faulty flanges were examined in BMW’s lab which concluded the cracks were caused by excessive tightening during servicing.

On Feb. 5, BMW decided to start notifying customers about a service action. On Feb. 26, the KBA, Germany’s federal motor transport authority, requested BMW increase its actions to a full recall.

BMW dealers will inspect recalled models and replace the original aluminum rear wheel flange with a new steel one.
