Adjustments for Competition 107
Front Suspension Adjustments
Both compression and rebound damping can be
increased by turning the adjuster clockwise.
Always start with full hard when adjusting
damping.
Do not turn the adjuster screw more than the
given positions or the adjuster may be damaged.
Be sure that the rebound and compression
adjusters are firmly located in a detent, and not
between positions.
NOTICE
Front Suspension Disassembly
• If your CRF is brand-new, put enough part-
throttle break-in time (about one hour) on it to
ensure that the suspension has worked in.
• For optimum performance, and extended fork
life, the fork should be completely
disassembled and cleaned after the first three
hours of riding. See the Shop Manual or your
Honda dealer for this service.
• When disassembling the fork, turn the
rebound (1) and compression (2) damping
adjusters counterclockwise to the softest
position to prevent damaging the adjustment
needle (be sure to record the number of turns
from the starting position).
Fork Springs
The fork springs in CRF’s are about right for
riders weighing between 68 and 73 kg (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
5 cm
3
(0.2 US oz, 0.2 Imp oz) 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: 303 cm
3
(10.2 US oz,
10.7 Imp oz)
Softer spring: 308 cm
3
(10.4 US oz,
10.8 Imp oz)
Stiffer spring: 306 cm
3
(10.3 US oz,
10.8 Imp oz)
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.
