The defect
Zero Motorcycle Inc. (Zero) is recalling certain 2021 SR, S, DSR, DS, FX, and FXS motorcycles. The DC-DC converter has an insufficient power output margin to operate the anti-lock braking system (ABS), instruments, lights, indicators, and any accessories that are connected to the accessory outlet at once.
The risk
The DC-DC converter can shut off when its power capacity is exceeded, shutting off the ABS, instruments, and lights, increasing the risk of a crash.
