THE PERFECT FIT
Rear Suspension Adjustments
Rear Suspensions
Polaris has a suspension to meet your needs. Each is designed and set
up to deliver a soft ride under average riding conditions. 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 suspension designs and adjustments involve a compromise, or
trade-off. For example, a suspension set up for snow-cross racing
would provide a very stiff ride on the trail. A suspension set up for
trail riding would bottom out harshly on a snow-cross course.
A decal outlining rear suspension set-up options is located either under
the hood or on the clutch cover. It provides a guideline for initial
suspension set-up. Additional adjustments can be made from this
point. Make adjustments to one area at a time so you can evaluate the
change. For further assistance, see your dealer.
Suspension Performance Tips
D
Rider weight usually determines the position at which the spring
preload should be set. However, this may vary with riding style.
With a little experimentation, each rider can find a preferred set-up.
These adjustments are easy to make, involve very little time or ef-
fort, and greatly affect the ride.
D
In deep snow, a new Hi-fax will offer improved performance over
worn Hi-fax. It can also improve top speed.
D
When riding on ice or hard-packed snow, adding a set of bogie
wheels to the rail may enhance the machine’s performance. Bogie
wheel kits are available from your dealer.
D
Polaris offers track kits for improved flotation in deep snow. See
your dealer for assistance.
NOTE: Keep the suspension pivot points lubricated. This will reduce
moisture and rust build-up and ensure proper function of the
suspension components. Grease rear suspension pivots before
adjusting the rear suspension. Refer to Suspension Maintenance on
pages 158-159.
