RIDE COMMAND

THE PERFECT FIT

SUSPENSION QUICK SET-UP GUIDE

The front and rear suspensions on your Matryx snowmobile are easy to adjust.
Just remember three simple steps:

1. Ride your snowmobile.

2. Adjust the

rear track shock spring

to tune

vehicle balance

(ski pressure and

weight transfer).

3. Adjust

shock clickers

(if equipped) to tune

ride quality

(stiffer or softer ride).

Step 1: Ride your snowmobile.

Ride the snowmobile in various terrain to fully experience the existing
suspension settings before making any adjustments.

Step 2: Adjust the torsion spring settings to tune vehicle balance.

After riding, you should be able to determine if the snowmobile needs more or
less transfer.

• For more transfer,

decrease

the torsion spring setting.

• For less transfer,

increase

the torsion spring setting.

If you prefer your snowmobile has lighter steering, decrease the torsion spring
setting or increase the front track shock spring preload.

Step 3: Adjust shock clickers (if equipped) for ride quality.

For models equipped with monotube shocks, always adjust the rear track shock
spring preload to enhance bottoming resistance.

For models with shock clickers, you can adjust the clickers to control bottoming
and adjust ride comfort.

• Turn a clicker counter-clockwise to decrease damping for a softer ride.
• Turn a clicker clockwise to increase damping for a stiffer ride and less

bottoming.

NOTICE

Always adjust the clicker at least one click below full stiff (full clockwise) or

shock damage will occur.

Test ride the snowmobile and continue making spring and clicker adjustments
until you achieve the perfect ride.

Front (IFS) shocks

SHOCK COMPRESSION DAMPING

The primary adjustment for overall vehicle balance is torsion spring preload.
Perform this adjustment first. After adjusting torsion spring preload to your
satisfaction, compression damping adjustments can be made to control ride
quality and bottoming resistance.

Compression damping can be adjusted at the front suspension and at the front
and rear track shock. Make adjustments in 2-click increments, then test ride.
When adjusting the front suspension, always adjust both clickers equally.

To stop bottoming

of the front or rear suspension (stiffer ride), rotate the clicker

(s) clockwise two clicks (as viewed from the top of the clicker), then test ride.
Repeat the adjustment until bottoming stops and the desired ride quality is
achieved.

For a more plush ride

at the front or rear suspension, rotate the clicker(s)

counter-clockwise two clicks, then test ride. Repeat the adjustment until the
desired ride quality is achieved.

108

THE PERFECT FIT

TORSION SPRING ADJUSTMENTS

To adjust rear torsion spring preload, rotate the three-position cam

using the

engine spark plug tool. Adjustment is easiest when the cam is rotated from low
to medium, and then to high. Rotating directly from low to high will require
significantly more effort. Different rate torsion springs are available if a firmer
ride is desired. See your dealer for more information.

NOTE

Adding 1+1 seat, or additional cargo may affect handling and require a spring

rate change.

FRONT TRACK SHOCK SETTINGS

Factory settings, combined with user adjustments to the rear track shock spring
(RTSS), should be all that’s necessary to provide the best riding experience for
most riders. The primary adjustment for overall vehicle balance is RTSS
preload. Perform this adjustment first.

Always perform shock spring preload adjustments with the weight of the vehicle
removed from the shock, limiter strap(s) disconnected, and the shock at full
extension.

NOTICE

Never adjust spring preload to an installed length longer than the factory length

or shorter than the minimum length as shown in the following chart. Damage to

the suspension could result. When decreasing preload, make sure at least two

turns of preload are holding the retainer against the spring.

REAR REAR SCISSOR STOP (RRSS) (IF
EQUIPPED)

REAR REAR SCISSOR STOP (RRSS) - ATTRIBUTES

Moving the RRSS to a higher position will have the following effects on the
suspension:

• Reduced weight transfer
• Improved chatter bump ride
• Improved cornering performance
• Increased load carrying capacity (2–up)

WEIGHT TRANSFER DURING ACCELERATION

The preferred method for controlling weight transfer during acceleration is by
adjusting the rear rear scissor stop (RRSS). The factory setting is the best for
most trail riding conditions.

To decrease weight transfer under acceleration (for improved cornering), rotate
the RRSS to a higher position.

To increase weight transfer or ski lift during acceleration, rotate the RRSS to a
lower position.

NOTICE

When adjusting for weight transfer, both the left and right rear rear scissor stop

adjuster blocks must be adjusted to the same position.

TRACTION PRODUCTS

TRACK STUDDING

Track studding will enhance braking control on hard-packed snow or ice, but
extreme caution is still required on such surfaces. Steering ability may be
reduced on hard-packed snow or ice.

When studded tracks are used, increased wear to the brake pads will result from
increased braking and requires increased brake inspection intervals.

Installing studs can also cause the track to stretch more than a non-studded
track. For this reason, POLARIS recommends inspecting track tension more
often and setting the tension at the preferred measurement.

121

THE PERFECT FIT

Always adhere to the manufacturer’s stud maintenance procedures and stud nut
torque specifications.

Before equipping your snowmobile with traction products, be aware of
regulations pertaining to the use of traction products in your area of operation.

STUDS

NOTICE

Failure to heed the following recommendations will result in tunnel or track

damage and a voided warranty.

Track damage resulting from improperly installed or maintained studs is not
covered under warranty. Use only POLARIS-approved traction products on your
snowmobile. See your dealer for more information about installing studs and/or
carbides.

NOTICE

Use of studs longer than the recommended length on snowmobiles equipped

with center coolers will result in center cooler damage or damage to the tunnel.

The Matryx chassis requires a stud protection kit to be installed before installing
studs or chassis damage will occur. This stud protection kit will protect against
chassis damage with the following track/stud combinations.

WARNING

Ice and snow build-up may interfere with the steering of your snowmobile,

resulting in serious injury or death. Keep the underhood area free of snow and

ice.

Before driving, manually turn the skis to the left and right to be sure ice and
snow are not interfering with full left and right steering. If difficulty is
encountered, remove ice and snow build-up that may be obstructing the steering
linkage.

THROTTLE LEVER

The throttle lever

and brake

are the primary controls of your
snowmobile. Always make sure
both are functioning properly.

127

PRE-RIDE INSPECTIONS

Squeeze the throttle lever to make sure it compresses evenly and smoothly.
When released, the lever should immediately return to the idle position without
binding or hesitation. If the throttle does not function smoothly, or if you discover
excessive lever freeplay, DO NOT start the engine. Have the throttle serviced
immediately.

BRAKES

Always check the following items for proper operation before starting the engine.

BRAKE LEVER TRAVEL

Squeeze the brake lever. It
should move no closer to the
handgrip than 0.5 in (1.3 cm)

A smaller distance indicates low
brake fluid level or air in the
hydraulic system. Refer to the
brake bleeding information on
page 166. Your dealer can
assist.

LEVER FEEL

If the brake lever feels “spongy” when squeezed, check the brake fluid level and
condition. Add fluid as needed. See the Brake Fluid section for details.

WARNING

Continued use of “spongy” brakes may cause a complete loss of brakes, which

could result in serious injury or death. Always have the brakes serviced at the

first sign of sponginess.

the lever lock is completely disengaged before operating the snowmobile.

129

PRE-RIDE INSPECTIONS

TRACK

Track damage or failure caused by operation on ice or poor lubrication
conditions voids the track warranty.

WARNING

Operating the snowmobile with a damaged track increases the possibility of

track failure, which could cause loss of control resulting in serious injury or

death. Always inspect the track for damage before using the vehicle.

WARNING

Use of traction products such as studs increases the possibility of track

damage and/or failure. Driving at high speeds for extended periods of time in

marginal lubrication could severely damage track rods, break track edges, and

cause other track damage. Examples of marginal lubrication would include

frozen bodies of water without snow cover, icy trails, and no-snow conditions.

HOOD AND SIDE PANEL FASTENERS

CAUTION

The hood and side panels of the snowmobile protect the operator from moving

parts. Never operate a snowmobile with the hood or side panels open or

removed. Always ensure that the hood and side panels are securely in place

before starting the engine.
