The oil seal behind the Mechanical Seal in the engine has Failed 3 times. Oil leaks from a small drain pipe on the bottom of the engine on the front right side, below the water pump assembly. When the Oil seal fails oil leaks from the drain pipe dripping oil in front of the rear wheel. I noticed this and see that the rear tire can contact the dripping oil and cause a slick and slippery situation where the rear wheel can loose traction and control, thus ending in bodily harm. The oil seal and mechanical seal failure is a know issue on the CRF 250 and 300 as they use the same bottom end of the motor. It is my advice for NHTSA to look into the issue have Honda re-engineer the Mechanical and Oil seals so there can be no failure. Luckily I have not had the oil seal fail to the point of an accident. I do not trust the motorcycle and will not ride it. Honda will not take it back thus I will sell or trade it to someone else with full disclosure. Sincerely, [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

May 24, 2021

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."

Consequence & remedy

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

Remedy: 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.
