REAR SUSPENSION ADJUSTMENTS
Adjustment Procedures
It is a recommended to break the suspension in for
approximately 150 miles (240 km) before fine tuning
adjustments are made.
All settings will vary from rider to rider, depending on rider
weight, vehicle speed, riding style, and trail conditions. We
recommend starting with factory settings and then
customizing each adjustment individually to suit rider
preference. The machine should be methodically tested
under the same conditions after each adjustment (trail and
snow conditions, vehicle speed, riding position, etc.) until
a satisfactory ride is achieved. Adjustments should be
made to one area at a time, in order to properly evaluate
the change.
The purpose of the front rear scissor stop (FRSS) is to
control the bump attitude of the rear suspension. As the
front torque arm (FTA) hits the bump, it forces the rear
scissor to collapse a predetermined amount, depending
on the FRSS block position.
This accomplishes two important things, it allows a lighter
spring rate on the FTA because it can borrow spring rate
from the rear torsion springs; and it prepares the rear
portion of the suspension for the bump, reducing
secondary kick back.
The FRSS is made of a resilient material allowing smooth
action and preventing any suspension component
damage.
Setting the Rear Suspension Ride Height
1.
To set up the rear suspension torsion spring preload,
measure the distance between the ground and rear
bumper with out the rider on the seat and the
suspension at full extension. This can be achieved by
lifting the rear of the machine so that the suspension
is off the ground and carefully setting the machine
down. Write this down as measurement “X”.
2.
Have the rider in full gear drop down on the seat, work
the suspension slightly by bouncing up and down and
sit in the seated riding position. With the rider in the
seated position measure from the ground to the
bumper in the same spot as you did for measurement
“X” and write it down as measurement “Y”.
3.
To determine the correct ride height, subtract
measurement X from measurement Y. (X - Y = ride
height).
4.
The ideal ride height is:
• EDGE RMK / EDGE = 4
”
(10cm)
• Widetrak = 1.5
”
(4cm)
5.
Adjust for the desired ride height by rotating the
torsion spring cams located on the rear of the torsion
spring.
