SUSPENSION
Suspension Set Up
A decal outlining rear suspension set up options is located either on the hood or
the clutch cover of your machine. These decals provide a guideline to be used for
initial suspension set up. Your set up may vary based on your desired riding style.
Xtra-12 Rear Suspension Adjustments
The primary rear suspension adjustments on Xtra-12 models are the compression
valving on both rear suspension shocks, the front track spring preload and the rear
torsion spring preload. It is important to note that adjusting the limiter strap does
not change weight transfer from the rear suspension to the skis as in a convention-
al suspension. Instead it will increase the entire rear suspension preload and de-
crease travel. To increase ski pressure the front rear scissor stop (FRSS) should
be set to low. To decrease ski pressure the FRSS should be set to high.
To properly adjust the rear suspension, start with the lightest preload setting that
will prevent heavy bottoming. Adjustments should be made to one area at a time,
in order to properly evaluate the change.
NOTE: Rear spring settings will affect ski-to-ground pressure. If ski pressure is
too light it may be desirable to tighten rear springs for an increase in ski-to-ground
pressure. It is also possible to reposition the FRSS for increased ski pressure. See
page 129.
Front Track Shock Spring
Front track shock spring preload is adjusted by grasping the spring and turning in
a clockwise direction to increase the preload. Turn in a counterclockwise direction
to decrease preload.
Rear Track Shock Spring
The rear track shock coil spring does not have a threaded adjuster. One option to
decrease preload for less aggressive riders is removal of the rear track shock
spring.
