THE PERFECT FIT
Rear 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 the first 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 rear
suspension.
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 measurement Y from
X (sag=X-Y). If the measured sag is
incorrect, adjust the FRA position and/or
rear torsion spring preload.
Tip: This is only an initial setup, and final spring preload may vary based on rider
preference and riding conditions. Accessory springs with a higher load
rating are available for some models. Please see your dealer for availability.
