IMPORTANT
Your Timbersled TRIO™Kit is exclusively designed for your vehicle. Please read the installation instructions
thoroughly before beginning. Installation is easier if the vehicle is clean and free of debris. For your safety, and to
ensure a satisfactory installation, perform all installation steps correctly in the sequence shown.
ASSEMBLY TIME
Approximately 18-30 minutes
NOTE
Additional time may be required for optional steps, or
to accommodate other installed accessories.

INSTALLATION INSTRUCTIONS
1. Place your bike on a suitable support stand so that
the ski is slightly off the ground and the bike is
secure from tipping over.
2. Make sure your upper fork tubes are in the stock
OEM position in the triple clamps. You may need
to raise or lower the upper fork tubes in the triple
clamps if they have been adjusted for specific
summer riding.
3. Remove rear bolt Aand aluminum spacer Bfrom
ski mounting block on spindle.
4. Remove the front fender from motorcycle.

Instr 9928531 Rev 01 2017-06 Page 5 of 8
5. Mount the upper TRIO mounting bracket as shown
to the top of your TRIO shock using the supplied
bolt. Make sure the Upper TRIO bracket is facing
forward in relation to the bike and the TRIO shock
reservoir is positioned towards the rear of the bike.
Torque to the specification listed below.
NOTE
KTM shock mounting bracket is symetrical. All other
models shock brackets have slotted holes on the
forward side of the bracket and must be mounted
with the slotted holes towards the front of the
motorcycle. See diagrams on pages 2 and 3 for
details.
TORQUE
50 Nm (40 ft/lbs)
6. Install the supplied bolts and spacers into the
upper mounting bracket. (Honda model shown)
NOTE
For Honda models install the two taller spacers to
the front side of the shock mounting bracket as
shown below. KTM, Husaberg, and Husqvarna
models require no spacers. Yamaha models require
four spacers of the same length that can be installed
in any orientation. Kawasaki models require four
spacers that will need to be installed with the larger
diameter portion of the spacer against the shock
mounting bracket.

Instr 9928531 Rev 01 2017-06 Page 6 of 8
7. Place the fender onto the TRIO shock assembly
with mounting bracket and hardware as shown.
Ensure that the mounting hardware, upper TRIO
bracket, spacers, and fender are lined up and the
hardware is through all necessary pieces.
8. Remount fender and TRIO assembly to the under-
side of the motorcycle's lower triple clamp. Torque
to the specification listed below.
TORQUE
13Nm (9.5 ft/lbs)
9. Place the lower eyelet of the TRIO shock into the
original rear spindle block spacer location. The
Timbersled TRIO shock is designed to have
around ¼" of pre-load when installed. This may
cause the TRIO shock to appear to be too long
when mounting into the rear spindle block spacer
location.
For easy installation while maintaining proper pre-
load of the TRIO shock, bleed off the air pressure
in the main shock chamber of the TRIO shock until
you can compress the shock the necessary
amount to line up the lower mounting eyelet of the
TRIO shock with the mounting hole of the spindle
block. Insert the M10x1.5" rear spindle block
bolt Cwhen aligned and tighten nut D. Torque to
the specifications listed below.
If your TRIO shock is too short for installation,
loosen the pinch bolts on the motorcycles triple
clamps and slide your motorcycle fork tubes up
until the center of the rear spindle block bolt hole is
¼" above the center of the lower TRIO shock
mounting eyelet. Tighten the motorcycle triple
clamp pinch bolts and torque to OEM
manufacturer’s specifications. This will ensure you
maintain a ¼" of preload on the TRIO shock when
installed. Next, bleed off the air pressure in the
main chamber of the TRIO shock until you can
compress the shock enough to line up the lower
eyelet of the shock with the mounting hole of the
spindle block. Insert the M10x1.5" rear spindle
block bolt Cwhen aligned and tighten nut D.
Torque to the specifications listed below.
IMPORTANT
Ensure the TRIO shock has a minimum of a ¼" pre-
load when installed. The TRIO shock can become
damaged if shock tops-out before motorcycle forks
do at full extension during riding.
TORQUE
50 Nm (40 ft/lbs)

AIR PRESSURE SET-UP
1. First, use the supplied shock pump to set the air
pressure in the EVOL chamber. To do so locate
the lower Schrader valve and attach the supplied
pump. See chart below for recommended setting.
IMPORTANT
To ensure proper ride characteristics always set the
pressure in the EVOL chamber FIRST.
NOTE
Make sure the ski is off the ground so the shock is
not under load and is fully extended before setting air
pressures.
EVOL CHAMBER PSI SETTINGS
RIDER PSI
Minimum 10 psi
125–150 lbs 20 psi
150–200 lbs 25 psi
200–250 lbs 30 psi
250–300 lbs 35 psi
Maximum 100 psi
2. Next, set the air pressure in the main shock
chamber. To do so locate the TRIO’s upper most
Schrader valve and attach the supplied pump.
Pump to recommended settings on the chart
below.
MAIN SHOCK CHAMBER PSI SETTINGS
RIDER PSI
Minimum 5 psi
125–150 lbs 10 psi
150–200 lbs 15 psi
200–250 lbs 20 psi
250–300 lbs 25 psi
Maximum 50 psi
3. Check to ensure all tools are accounted for and all
steps have been completed.
WARNING
DO NOT exceed maximum pressures. Contents of
shock are under pressure: Never incinerate or
puncture; and never disassemble without consulting
service manual; as any of those may result in serious
INJURY or DEATH

TUNING TIPS
EVOL AIR CHAMBER - EXTRA VOLUME
1The infinitely adjustable pressure setting in the extra
volume (EVOL) air chamber regulates spring rate in
the final portion of the stroke and controls the bottom-
out characteristics of the shock.
Increasing air pressure in the EVOL air chamber will
give a more progressive spring curve to protect
against harsh bottom-outs. Decreasing air pressure
will provide a more linear curve to maximize usable
travel.
When combined with the infinite adjustability of the
main air spring, the EVOL air chamber allows the
shock's spring curve to be tuned for any conceivable
rider weight and/or terrain condition. The pressure in
the EVOL air chamber is adjusted to control the
bottom-out characteristics of the shock. More details
at http://www.ridefox.com/technology.
FOX FLOAT - MAIN CHAMBER
Your TRIO main shock chamber is a FOX FLOAT
shock specifically designed for Timbersled to increase
spring rate, maintain ride height, and improve the
overall ride and handling characteristics of the
snowbike.
For Timbersled TRIO shock applications the
recommended main chamber air pressure settings
table on page 7 of your installation instructions are
unique to the Timbersled TRIO application and should
be followed to achieve the best overall ride
characteristics.
2The spring rate is controlled by air pressure in the
main body. Air pressure is infinitely adjustable making
the FLOAT the most progressive and adjustable air
shock on the market.
