Plain-English summary
Zero Motorcycles Inc. is recalling certain 2021 SR, S, DSR, DS, FX, and FXS motorcycles. The recall involves 64 affected vehicles. The defect is located in the DC-DC converter, which has an insufficient power output margin to operate the anti-lock braking system (ABS), instruments, lights, indicators, and accessories simultaneously.
When the power capacity of the DC-DC converter is exceeded, it can shut off. This shutdown disables the ABS, instruments, and lights, which increases the risk of a crash. No specific dates or geographic distribution details beyond the model years are provided in the source text.
Zero will notify owners, and dealers will replace the DC-DC converter free of charge. The recall began on October 26, 2020. Owners may contact Zero customer service at 1-888-841-8085 or the NHTSA Vehicle Safety Hotline at 1-888-327-4236.
