Received: 24/05/2021▼
Defect Description

Honda (American Honda Motor Co.) is recalling certain 2020-2021 Super Cub C125, CB500X, CB650R, CBR300R, CBR500R, CBR650R, Rebel 300, Rebel 500, Monkey, 2020 CRF250L, GROM, 2021 CRF300L, and CB500F motorcycles. The rear reflector lens may not reflect brightly enough. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 108, "Lamps, Reflective Devices, and Associated Equipment."

Safety Hazard / Consequence

A dim rear reflector may reduce the visibility of the motorcycle to other drivers, increasing the risk of a crash or injury.

Factory Remedy & Repair Action

Dealers will replace the rear reflector, free of charge. Owner notification letters were mailed July 7, 2021. Owners may contact Honda customer service at 1-866-784-1870. Honda's number for this recall is KM3.

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.nhtsa.gov.
