NHTSA #20V495000EQUIPMENT:OTHER:LABELS

Received: 20/08/2020▼

Defect Description

BMW of North America, LLC (BMW) is recalling certain 2021 R 1250 RT, R 1250 R, R 1250 RS, R 1250 GS and R 1250 GS Adventure motorcycles. The tire pressure labels may not remain affixed to the motorcycle frame. As a result, these motorcycles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 120, "Wheels and Rims-Other Than Passenger Cars."

Safety Hazard / Consequence

If the label detaches from the motorcycle, proper tire pressure information may not be readily available. This could result in the rider improperly filling the tires which may affect motorcycle handling and control, increasing the risk of a crash.

Factory Remedy & Repair Action

BMW will notify owners, and dealers will replace the tire pressure label, free of charge. The recall began October 19, 2020. Owners may contact BMW customer service at 1-800-525-7417.

Manufacturer Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
