What is wrong

Honda (American Honda Motor Co.) is recalling certain 2019-2020 CB500X and CBR500R ABS motorcycles. Excessive grease in the ABS modulator may collect debris, which can get stuck in the check valve and cause a brake fluid leak.

What can happen

A brake fluid leak can reduce braking performance and increase the risk of a crash.

The remedy

Dealers will inspect the lot number on the ABS modulator, and replace the modulator as necessary, free of charge. Owner notification letters were mailed November 12, 2021. Owners may contact Honda Powersports customer service at 1-866-784-1870. Honda's number for this recall is KM6.

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.
