Summary
Model Year 2020 Zero SR/F Rear Rotor Bolts Re-Torque Service Campaign - Zero Motorcycles has determined that the rear rotor bolts on certain model year 2020 Zero SR/F motorcycles were insufficiently torqued. Owners of these motorcycles may find that these bolts will back out of their sockets slowly and scratch or damage the swingarm of their motorcycles. If the bolts were to back out sufficiently to contact the swingarm, this would also cause objectionable noise while riding. Owners should take their motorcycles to their dealer to have the rear rotor bolts re-torqued to 26 ft-lbs/36 Nm. As long as there is no damage to the bolts and they move when re-torqued, the rear rotor bolts do not need to be replaced and the existing lock patch will secure them in place. If the bolts are damaged or removed first, then they should be replaced by the dealer.

Model Year 2020 Zero SR/F Rear Rotor Bolts
Re-Torque Service Campaign
Purpose
Zero Motorcycles has determined that the rear rotor bolts on certain model year 2020 Zero SR/F
motorcycles were insufficiently torqued. Owners of these motorcycles may find that these bolts will back out
of their sockets slowly and scratch or damage the swingarm of their motorcycles. If the bolts were to back
out sufficiently to contact the swingarm, this would also cause objectionable noise while riding.
Owners should take their motorcycles to their dealer to have the rear rotor bolts re-torqued to 26 ft-lbs/36
Nm. As long as there is no damage to the bolts and they move when re-torqued, the rear rotor bolts do not
need to be replaced and the existing lock patch will secure them in place. If the bolts are damaged or
removed first, then they should be replaced by the dealer.
Applicable Models
All 2020 Zero SR/F motorcycles manufactured before December 19, 2019. The last five digits of the vehicle
identification number of affected motorcycles will be 13511 or lower.
Tools Required
T40 Star Drive Bit Socket
Torque Wrench (capable of 26 ft-lbs/36 Nm)
Parts Required
None.
However, if the rear rotor bolts are damaged in the process or removed prior to re-torquing them, please
replace with the following part number:

Process Steps
1. Confirm that you have all required tools and parts before starting this re-torque process. The rear rotor
bolts only need to be replaced if they are damaged or have been removed, which strips the pre-applied lock
patch.
2. Lift the rear wheel using a rear paddock stand or other suitable method.
CAUTION: Do not lift the Zero SR/F by placing a scissor jack or other lift under the controller carrier
. Lifting
the motorcycle in this manner could result in damage to the controller and other components.
3. Using the T40 Star Drive Bit Socket and a Torque Wrench, re-torque the existing rotor bolts one at a time
to 26 ft-lbs/36 Nm. The existing paint pen marks should reflect that the head of the bolt has rotated in this
process.
If you have any questions, please contact the Customer Service Team.

4. If any of the rear rotor bolts is damaged or is first removed, it should be replaced. Remove such bolts one
at a time and replace. Torque each bolt to the 26 ft-lbs/36 Nm.
5. Once all five rotor bolts have been re-torqued or replaced, lower the rear wheel of the motorcycle.
