Suspension
Refer to Safety Precautions on page 27.
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 Honda dealer for
further inspection. Your dealer is qualified to
determine whether or not replacement parts or
repairs are needed.
• When your CRF is new, break it in for
approximately 1 hour to ensure that the
suspension has worked in (page 23).
• 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 118 for fork disassembly.
• Replace the fork oil every 3 races or 7.5 hours
of running. See page 93 for oil capacity
adjustment after changing the fork oil.
• Replace the damper oil every 9 races or 22.5
hours of running. See page 121 for damper
fork oil replacement.
• Use KHL15-11(KYB) 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.
• Refer to Suspension Adjustment Guidelines
(page 135). Make all rebound and compression
damping adjustments in one-click increments.
(Adjusting two or more clicks 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.
3. Inspect the wear rings (3) for wear or damage.
Replace the wear ring if it is 1.5 mm (0.06 in)
or flat with the outer tube (4). Remove the fork
leg when replacing the wear ring.
Install the wear ring with its end gap (5) facing
rearward.
4. Make a quick check of fork operation by
locking the front brake and pushing down on
the handlebar several times.
