2020 ZERO SR/FTransport Canada Recall #2021654
The official notice
Defect
On certain motorcycles, the rear brake rotor bolts may not have been tightened properly. As a result, the bolts could loosen over time and contact the rear swingarm or brake caliper bracket. This can cause reduced braking. Note: A rider may hear an abnormal noise if a bolt contacts the rear swingarm.
Safety Risk
Reduced braking can cause an increased stopping distance and create the risk of a crash.
Remedy
Zero Motorcycles will notify owners by mail and instruct you to take your motorcycle to a dealer to inspect and re-tighten the rear brake rotor bolts. Any damaged bolts will be replaced.
