Zero Motorcycles Issues Recall on DS, FX and Other Dual Sport Models


Zero Motorcycles has issued a recall on certain dual sport models as well as other units in its street-oriented lineup. According to the notice issued by the National Highway Traffic Safety Administration (NHTSA), a total of 64 motorcycles for the 2021 model year could be affected. The models included in the recall are the 2021 SR, S, DSR, DS, FX and FXS.

The recall was initiated after it was discovered that some models were assembled with a DC-DC converter which may have insufficient output power margin to support all power demands. Specifically, the faulty converter is unable to support the operation of the anti-lock braking system (ABS), instruments, lights, indicators and any accessory connected to the accessory socket at the same time.

What could happen

The NHTSA recall report states that if the power capacity of the DC-DC converter is exceeded, it may temporarily shut down without warning the rider. If this happens when the anti-lock braking system is activated, the vehicle’s ABS, instruments and lights will temporarily stop working, which could increase the risk of an accident.

How to fix it

Zero will notify owners and ask dealers to replace the DC-DC converter free of charge. The remedy for this defect is that an authorized Zero Motorcycles dealer replace the incorrect Revision B DC-DC converter with the correct Revision A, which is listed on the label.

The correct Revision A DC-DC converter can be distinguished from the incorrect Revision B converter by examining the label on the silver end of the split component bracket.

If you choose to ride your suspicious motorcycle before asking your dealer to perform this replacement, Zero says you should be aware that this issue can occur and avoid using any accessories on the accessory socket.

The recall is expected to begin on November 2, 2020. Owners can contact Zero Customer Service at 1-888-841-8085. The zero number for this recall is SV-ZMC-021-019.
