Zero Motorcycles is recalling certain 2021 model motorcycles due to a faulty DC-DC converter.  A small number of 2021 model year Zero S, SR, DS, DSR, FX, and FSX models may be affected.   These motorcycles contain a DC-DC converter that may have an insufficient power output margin.

According to Zero:

If a DC-DC converter does not have enough power output margin to support all power demands, it may temporarily shut off when its power capacity is exceeded, with no warning to the rider. Should this occur during an Anti-Lock Braking System (ABS) activated event, the ABS and all vehicle lights would temporarily stop functioning, which could increase the risk of a crash.

In total, only 64 motorcycles built between August 19, and October 5, 2020, have this potential defect.

Zero will contact all owners of the affected motorcycles.  Owners should take the recalled motorcycle to a dealer for repair.  Dealers will replace the existing revision B DC-DC converter with a revision A DC-DC converter free of charge.  This recall will begin on November 2, 2020.

For additional information, owners may contact Zero customer service at 1-888-841-8085 and should cite recall number SV-ZMC-021-019.  Or owners can contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 or go to
