The rear suspension is adjustable for pre-load
only.

To change the rear suspension spring pre-
load setting, insert the adjustment tool
located in the base of the pillion seat into the
hole provided in the adjuster ring.
Maintenance and Adjustment
Turn the adjuster ring clockwise to increase
spring pre-load, and
decrease spring pre-load. When delivered
from the factory, the pre-load adjuster will be
set at position 1.
Warning
Ensure that the adjusters are set to the
same setting on both rear suspension
units. Settings that vary from left to right
may affect handling and stability resulting
in loss of motorcycle control and an
accident.

Suggested Suspension Settings

Adjuster settings are counted from position
one with position one being with the adjuster
turned fully anti-clockwise. There are five
positions in total. Position 1 gives the
minimum amount of spring pre-load.
