MAINTENANCE
Rear Suspension
Adjust Rear Shock Absorber
4. Remove the motorcycle lift apparatus and return the motorcycle to the ground.
5. Load the motorcycle with all the things you intend to carry (cargo and accessories). Sit in the operator's seat
with your riding gear on, and if you plan on carrying a passenger, have them sit in the passenger seat with their
riding gear on.
6. Have your assistant bounce the rear suspension a few times by pushing down on the rear fender slowly and
releasing. Make sure the suspension moves freely without binding.
7. Without moving the motorcycle, have your assistant measure the distance from the center of the rear axle to the
bottom of the rear fender directly above the axle. This measurement must be taken from the same locations
recorded in step 2.
8. Subtract the second measurement (step 7) from the first
measurement (recorded in step 2). The difference is called "sag"
and should be 3/4 to 1 1/4 inch (19 to 32 mm). Adjust the shock
absorber preload and recheck the sag if necessary. Rotate
adjuster nut clockwise (viewed from the rear of shock absorber)
to DECREASE the sag measurement, and counterclockwise to
INCREASE the sag measurement.
