Safety Recall: 2021 DC-DC Converter NHTSA Campaign Number: 20V-640
Purpose
Zero Motorcycles has determined that a defect, which relates to motor vehicle safety, exists on certain 2021 Model Year SR, S, DSR, DS, FX and FXS model motorcycles built between August 19, 2020 and October 5, 2020. The subject motorcycles were assembled with a DC-DC converter that may have insufficient power output margin. 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 the interest of motor vehicle safety and customer satisfaction, Zero Motorcycles has elected to initiate a voluntary recall (Campaign 20V-640) to remedy this defect. The remedy of this defect is to have Zero Motorcycles dealers replace the revision B DC-DC converter with a revision A
As required by law, you may sell but NOT DELIVER any affected motorcycles to your customers until the remedy is completed.
Applicable Models
The recall population of 64 motorcycles includes selected 2021 model year Zero SR, S, DSR, DS, FX and FXS built between August 19, 2020 and October 5, 2020.

A sample of the owner letter is attached. Zero will also try to contact these customers via email.
To protect the safety of our riders, it is our mutual responsibility to ensure the recall upgrade is performed on all affected motorcycles. Therefore, we strongly encourage you reach out to your customers to make sure that they are aware of this program.
