What's wrong, in plain English

Some Honda motorcycles, including the CMX500 and CRF300L, have a rear reflector lens that may not reflect light as brightly as it should. This lens is part of the rear lighting equipment, and its dimness means the motorcycle does not meet a federal lighting safety standard.

What you should do

1. Check your VIN at nhtsa.gov/recalls to see if your motorcycle is included.
2. Contact a Honda dealer, or call Honda customer service at 1-866-784-1870.
3. Dealers will replace the rear reflector, free of charge.

Where do I find my VIN, and what do I tell the dealer?
