General
The rear shock absorber spring preload can be adjusted for the weight the motorcycle is to carry and has five preload graduations. Notice the adjustment settings as you turn the collar.
Use the adjustment setting numbers as a reference for equal adjustment of shock absorbers on both the right and left side of the motorcycle.
