Suspension

Refer to Safety Precautions on page 19.
Loose, worn, or damaged suspension components
may adversely affect the handling and stability of
your CRF. If any suspension components appear
worn or damaged, see your dealer for further
inspection. Your dealer is qualified to determine
whether or not replacement parts or repairs are
needed.

Front Suspension Inspection

• When your CRF is new, break it in for
approximately 1 hour to ensure that the
suspension has worked in (page 16).
• After break-in, test run your CRF with the
front suspension at the standard setting before
attempting any adjustments.
• For optimum fork performance, we
recommend that you disassemble and clean the
fork after riding your CRF for 3 hours.
See page 94 for fork disassembly.
• Replace the fork oil every 3 races or 7.5 hours
of running. See pages 73, 74 for oil level
adjustment after changing the fork oil.
• Use HP Fork Oil, SS-19 or an equivalent
which contains special additives to assure
maximum performance of your CRF's front
suspension.
• Periodically check and clean all front
suspension parts to assure top performance.
Check the dust seals for dust, dirt, and foreign
materials. Check the oil for any contamination.

Servicing Your Honda
• Refer to Suspension Adjustment Guidelines
(page 107). Make all rebound and compression
damping adjustments in 1/4 turn increments.
(Adjusting 1/2 or more turns at a time may
cause you to pass over the best adjustment.)
Test ride after each adjustment.
• If you become confused about adjustment
settings, return to the standard position and
start over.
• If the fork is still too stiff/soft after adjusting
compression damping, determine which
portion of the travel is still too stiff/soft. This is
an important step that will help you solve
suspension problems.
1. Make sure that the fork protectors (1) and dust
seals (2) are clean and not packed with mud
and dirt.
2. Check for signs of oil leakage. Damaged or
leaking fork seals should be replaced before
your CRF is ridden.

Replace the wear ring if it is 0.06 in (1.5 mm)
or flat with the outer tube (4).
Remove the fork leg when replacing the wear
ring (page 94).
Install the wear ring with its end gap (5) facing
