The contact owns a 2020 Zero SR/S motorcycle. The contact stated that while riding at an undisclosed speed and coming to a full stop, the rear brake was applied; however, the motorcycle rolled backward. The motorcycle was taken to the dealer where it was diagnosed that the rear brake and caliper were engaged while riding, causing the rear brake and caliper to melt. The dealer informed the contact that the rear brake and caliper needed to be replaced. The motorcycle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 1,200.
Zero Motorcycles Inc. (Zero) is recalling certain 2020 SR/F and SR/S motorcycles. The front brake switch can fail from water getting into the switch.
Consequence & remedy
Consequence: An inoperable front brake switch will not illuminate the brake light when the rider applies the front brakes. Following vehicles may not realize the motorcycle is braking. Cruise control will not shut off with the application of the front brakes. Both conditions increase the risk of a crash.
Remedy: Zero will notify owners, and dealers will the replace the front brake switch, free of charge. The recall began November 30, 2020. Owners may contact Zero customer service at 1-888-841-8085. Zero's number for this recall is SV-ZMC-021-020.
