THE PERFECT FIT
IQ 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.
NOTE: 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 measure-
ment X. This is measurement Y.
To determine sag, commonly referred to as ride-in, subtract measure-
ment Y from X (sag=X-Y). If the measured sag is incorrect, adjust the
FRA position and/or rear torsion spring preload.
NOTE: This is only an initial setup, and final spring preload may vary based on
rider preference and riding conditions.
NOTE: Accessory springs with a higher load rating are available for Touring
models with the IQ Comfort rear suspension, P/N 7043368 (left) and
P/N 7043369 (right). Please see your dealer for availability.
