THE PERFECT FIT
Rear Suspension Adjustments
Initial Spring Preload Setting (Sag Method)
To set up the rear suspension torsion spring preload, measure the dis-
tance between the ground and rear bumper. This is measurement X.
Take the first measurement with no rider and with the rear suspension at
full extension.
Tip: The rear bumper may need to be raised slightly to fully extend the rear sus-
pension.
Next, have the rider drop down hard on the seat and bounce up and
down several times, collapsing the rear suspension. With the rider
seated, measure the distance between the ground and the rear bumper at
the exact location 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 page 53.
The ideal amount of sag for this rear suspension is 2.5 inches (6.4 cm)
(X-Y=2.5 in./6.4 cm).
