FRONT SUSPENSION
The fork should always be adjusted for the rider’s
weight and track conditions by using one or more of the
following methods.
Basically, there are four adjustments you can make to
the front suspension:
•
Fork springs—Optional spring is available in softer
and stiffer type than the standard rate. (page 10)
•
Rebound damping—Turning the rebound damping
screw adjusts how quickly the fork extends.
•
Compression damping—Turning the compression
damping screw adjusts how quickly the fork com-
presses.
•
Oil volume—The effects of higher or lower fork oil
level are only felt during the final 3.9 in (100 mm) of
fork travel.
NOTE:
•
Air is an unstable gas which builds up pressure as
it is worked (such as in a fork). Air pressure acts as
a progressive spring and affects the entire range of
fork travel. This means the fork action on your CR
will get stiffer during a race. For this reason, release
built-up air pressure in the fork legs between mo-
tos. Be sure the fork is fully extended with the front
tire off the ground when you release the pressure.
NOTE:
•
The inverted fork on your CR features sealed damper
cartridges with dual (separate air and oil) chambers
to prevent aeration. The design also isolates the oil
in each fork tube/slider, which may contain air
bubbles and/or metal particles, from the sealed
cartridge to provide more consistent damping.

Fork Springs
The fork springs in CR’s are about right for riders
weighing between 150 and 160 lbs (less riding gear). So
if you’re a heavier rider, you have to go up on the oil
level or get a stiffer spring. Do not use less oil than the
minimum specified for each spring or there will be a
loss of rebound damping control near full extension.
If the fork is too hard on big bumps, turn the damping
adjuster counterclockwise 1-turn and lower the oil level
in increments of 0.2 oz (5 cc) in both fork legs until the
desired performance is obtained. Do not, however,
lower the oil level below the minimum oil level.
Minimum oil capacity:
Standard spring: 11.0 US oz (324 cm
3
)
Softer spring:
11.1 US oz (329 cm
3
)
Stiffer spring:
10.8 US oz (319 cm
3
)
NOTE:
•
When adjusting oil levels, bear in mind that the air
in the fork will increase in pressure while riding;
therefore, the higher the oil level, the higher the
eventual pressure of any air in the fork.
