2021 Honda Cmx500
Limited data: few reports on file, read the verdict loosely
Too few owner complaints are on file to affirm this car. Treat it as unproven, not endorsed, and lean hard on a professional pre-purchase inspection.

The math, shown
Full methodology →How it crashes
NHTSA’s own crash tests, separate from the reliability score above.
NHTSA hasn’t published a crash-test rating for this model year. That’s common for lower-volume or older models. It doesn’t mean the car is unsafe, just that this program hasn’t tested it.

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