THE PERFECT FIT
Suspension Adjustments
Initial Spring Preload Setting (Sag Method)
To set up the rear suspension torsion
spring preload, measure the distance
between the ground and rear bumper.
This is measurement X.
Take this measurement with no rider
and with the rear suspension at full
extension.
TIP:The rear bumper may need to be
lifted upward slightly to fully extend
the suspension.
Next, have the rider drop down hard
on the seat and bounce up and down
several times, collapsing the rear sus-
pension. With the rider seated, mea-
sure the distance between the ground
and the rear bumper at the exact loca-
tion used for measurement X. This is
measurement Y.
To determine sag, commonly referred to as ride-in, subtract measure-
ment Y from X (Sag=X-Y). Adjust sag by rotating the torsion spring
preload cams located on the rear torque arm. See illustration. The ideal
amount of sag for this rear suspension is five inches (12.7 cm) (X-Y=5
in./12.7 cm).
If the rear suspension rides in less than four inches or more than six
inches with the torsion spring preload cams at their maximum range of
adjustment, optional torsion springs (softer or stiffer, respectively) may
be required. This is only an initial setup, and final spring preload may
vary based on rider preference and riding conditions.
