Updated. BMW Motorrad has begun the recall process for K and R models produced from November 2003 to April 2011 due to a problem with the rear wheel carrier flange. We’re told this will affect 367,000 motorcycles worldwide, including 43,425 units in the U.S. According to BMW, cracks could develop in the rear wheel flange if the brake disc bolts or wheel lugs are tightened excessively during maintenance. BMW will replace the aluminum wheel flanges with a stronger steel component.
The recall has not yet been officially announced in the US by the National Highway Traffic Safety Administration although we expect it to be initiated shortly. Dealers we have contacted do not have any additional information and, therefore, owners should wait for the official announcement before contacting them for repair.
Here is the information from Canada’s Transport Recall #2015101: “On certain motorcycles, the threaded holes on the rear wheel flange could crack if the wheel bolts are tightened beyond the specified torque limit during servicing. Over time, this could allow the bolts to back out of their threaded holes, causing the rear wheel to become loose. This could result in a loss of stability of the motorcycle, and increase the risk of a crash causing injury and/or property damage. Correction: Dealers will replace the aluminum rear wheel flange with a steel flange”
Update (3/30/15): The recall has been made official with the National Highway Traffic Administration (NHTSA Campaign Number: 15V141000). BMW expects the recall to begin in the US on April 21, 2015. BMW will notify owners and dealers will replace the rear wheel flange free of charge. Owners may contact BMW customer service at 1-800-525-7417 for additional information.
The NHTSA report also describes the events leading up to the recall. According to BMW, they became aware of the issue on August 6, 2014 following an accident in Spain with a “high mileage” 2004 R1200RT. That customer’s motorcycle was reviewed further and by January 2015 found to be in “overall good condition, and that the customer had performed all required services” with BMW concluding cracks in the rear wheel flange were due to “excessive applied torque during servicing.”
Also in January, BMW inspected 58 customer motorcycles (with 2,500 to 40,000 miles on them) in Munich, Germany and found three with flange cracks. These parts were tested in a laboratory and found to also have received excessive tightening.
BMW therefore decided on February 5, 2015 to notify customers of a “service action.” Prompted by a letter from the German regulatory authority, BMW decided on March 5 to conduct a voluntary recall. BMW has received one report of an accident related to this issue with the rider and passenger experiencing bruises and abrasions.
