WASHINGTON, D.C. - Zero Motorcycles Inc. is recalling certain 2014 model year motorcycles for a possible manufacturing defect that would allow the motor rotor to contact the stator while the bike is operational, NHTSA announced.
If the rotor contacts the stator, the motor could seize. This could lock up the rear wheel and increase the risk of a crash, according to the manufacturer.
About 94 models are involved in the recall. They are:
- 2014 Zero SRs manufactured between Dec. 30, 2013, and Feb. 20, 2014,
- 2014 Zero S motorcycles manufactured from Dec. 26, 2013, through Feb. 18, 2014,
- 2014 Zero DSs made from Jan. 24, 2013, through Feb. 4, 2014, and
- 2014 Zero FXs made from Jan. 14 through Jan. 27, 2014.
Dealers are being asked to conduct an in-motorcycle stationary screening test of the motor and determine whether replacement is needed. The motor is supplied to Zero by Motenergy Inc. of Slinger, Wis.
"Dealers and owners will also be advised to keep motor rpm below 5,000, should they choose to ride the suspect motorcycles prior to running this screening test," Richard Kenton, Zero's director of customer service, informed NHTSA. "5,000 rpm corresponds to the following approximate top speed per model: 85 mph on SR, 79 mph on S, 82 mph on OS and 71 mph on FX."
