Rear Suspension Inspection
The swingarm is controlled by one hydraulic
shock absorber with an aluminum reservoir for
oil and nitrogen gas pressure. The gas pressure in
the reservoir is contained within a rubber bladder.
The shock absorber’s spring pre-load and
damping adjustments (compression and rebound)
should be adjusted for the rider’s weight and
track conditions (pages 130 – 133).
Do not attempt to disassemble, service, or
dispose of the damper; see your dealer. The
instructions found in this owner’s manual are
limited to adjustments of the shock assembly only.
• When your CRF is new, break it in for
approximately 1 hour with the standard
suspension settings before attempting to adjust
the rear suspension.
• Refer to
Suspension Adjustment Guidelines
(page 133). Make all rebound and
compression damping adjustments in one
click or 1/12 turn increments.
(Adjusting two or more increments or turns
at a time may cause you to pass over the best
adjustment.) Test ride after each adjustment.
• If the rear suspension is too stiff/soft, adjust
it by turning all the compression and rebound
adjusters according to the procedures
described in page 127. After adjusting the
adjusters simultaneously, suspension may be
fine-tuned by turning one of the compression
and rebound damping adjusters in one click or
in 1/12 turn increments.
• If you have a problem finding an acceptable
adjustment, return to the standard position and
begin again.
1. Bounce the rear of the motorcycle up and
down and check for smooth suspension
action.
2. Lift the subframe to the upright position
(page 39).
3. Check for a broken or collapsed spring.
4. Check the shock absorber (1) for a bent rod
or oil leaks.

5. Push the rear wheel sideways to check for
worn or loose swingarm bearings. There
should be no movement. If there is, have the
bearings replaced by your dealer.
