Rear Shock Preload (Ride Height) Inspection

Image
Periodically inspect rear shock preload. For the most comfortable ride and proper ground clearance, adjust preload if ride height is out of specification.
  1. Verify that tire pressure is at specification. See Tire Pressure.
  2. Secure the motorcycle in an upright position by clamping the front wheel in a wheel vise.
  3. Remove the right-hand saddlebag (if equipped).
  4. Apply a strip of tape to the rear fender directly over the center of the rear axle.
  5. Using a suitable lift, raise the motorcycle until the rear shock is completely extended.
  6. Measure the distance (in millimeters) from the center of the rear axle to the bottom of the tape. Record the results as measurement M1.
  7. Lower the motorcycle and remove the lift.
  8. Load the motorcycle with all intended cargo. Wearing your riding gear, bring the motorcycle to the upright position and sit on the operator's seat. If you plan to carry a passenger, have the passenger (with riding gear) sit on the passenger seat.
  9. Have an assistant measure in the same location. Record the results as measurement M2.
  10. Subtract measurement M2 from M1. The result is the measured rider sag. (M1-M2=Sag). Adjust preload as needed.
