On June 8, 2022, Zero Motorcycles issued a safety recall on certain 2022 SR and SR/F motorcycles due to the possibility of an incorrect front brake caliper bolt having been installed. Affected bikes may have had front brake caliper bolts installed with an incorrect thread pitch, which could cause damage to the mounting threads on the fork. If this happens, the calipers could reduce the clamping load, causing the caliper to loosen, reducing available braking force. As a result, riders could potentially crash.
Approximately 23 motorcycles, or an estimated 10 percent of the population, are believed to be affected. All the 2022 SR and SR/F units with this issue passed through the same production station between April 22, 2022 and April 27, 2022. The last five digits of the VINs on affected bikes are between 21423 and 21486.
