THE PERFECT FIT
Rear Suspension Adjustments
Rider weight, riding style, trail conditions, and vehicle speed all affect
suspension action.
Each rear suspension can be adjusted to suit rider preference and deliver
excellent performance for a given set of conditions. However, all sus-
pension designs and adjustments involve a compromise, or trade-off.
For example, a suspension set up for snowcross racing would provide a
very stiff ride on the trail. A suspension set up for trail riding would
bottom out harshly on a snowcross course.
Refer to the suspension setup label on your snowmobile, or see your
POLARIS dealer for initial suspension setup information. Additional
adjustments can be made after initial setup. Make adjustments to one
area at a time so you can evaluate the change. For further assistance, see
your dealer.
