TUNE YOUR RIDE
Rear Spring Preload
Rear spring preload has an effect on
comfort, ride height and load compen-
sation.
Also, adjusting rear spring preload
shifts more or less weight to the snow-
mobile front end. As a result, more or
less weight is applied to the skis. This
has an effect on performance in deep
snow, steering effort and handling.
Slight suspension bottoming occurring
under the worst riding conditions indi-
cates a good choice of spring preload.
