The investigation covers 430,000 Harley-Davidson motorcycles with model years between 2008 and 2011 and that have an anti-lock braking system, the National Highway Traffic Safety Administration said today.
Riders reported that the brakes on the hand lever and foot pedal did not work, causing one driver to crash into a garage door. NHTSA said it received 43 complaints, three reports of crashes and two reports of injuries.
The agency said it is possible that some riders who experienced brake failure did not change the motorcycle's brake fluid every two years as recommended by Harley-Davidson.
Milwaukee-based Harley-Davidson Inc said today that it is aware of the investigation and is cooperating with NHTSA.
