WASHINGTON, D.C. - Zero Motorcycles is recalling certain model year 2012-13 XU, S, DS motorcycles and 2013 FX bikes because controller firmware may shut off power to the motor, NHTSA announced.

Roughly 667 motorcycles are affected, according to Zero.

The bikes "have a controller firmware that may react to infrequently encountered signal faults by discontinuing controller power to the motor," stated Richard Kenton, director of customer service at Zero, in the company's Dec. 13 notification to NHTSA. "Should one of these faults occur while the motorcycle is being ridden, the controller's response may result in an inadvertent quits-while-running condition, which could lead to a crash."

The controller firmware is supplied by Sevcon Ltd. of the United Kingdom. Zero said it is not aware of any accidents or injuries caused by this condition.

Zero will notify owners. Dealers are asked to update the controller firmware, free of charge. The recall is expected to begin in mid-January.
