Suspension
Refer to Safety Precautions on page 25.
Loose, worn, or damaged suspension components
may adversely affect the handling and stability of
your motorcycle. 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 21).
• 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 107 for fork disassembly.
• Replace the fork oil every 7.5 hours of
running. See page 84 for oil level adjustment
after changing the fork oil.
• Replace the damper oil every 22.5 hours of
running. See page 111 for oil level adjustment
after changing the damper oil.
• Use Pro Honda HP Fork Oil 5W 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.
• Refer to
Suspension Adjustment Guidelines
(page 125). 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 stif f/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 0.06 in (1.5 mm)
or flat with the outer tube (4).
When replacing the wear ring, remove the
fork leg (page 107).
Install the wear ring with its end gap facing
rearward.

the handlebar several times.
