146 Adjustments for Competition
Front Suspension Adjustments
Compression Damping Adjustment
This adjustment affects how quickly the fork
compresses. The fork compression damping
adjuster has 16 clicks or more. Turning the
compression damping adjuster screw (1) one full
turn changes the adjuster 4 clicks. To adjust the
adjuster to the standard position, proceed as
follows:
Turn the adjuster clockwise (harder) until it will no
longer turn (lightly seats). Turn the adjuster
counterclockwise (softer) until it clicks. This click
is position 1.
(CRF250R)
The standard position is 9 clicks.
(CRF250RX)
The standard position is 12 clicks.
Make sure that both fork legs are adjusted to the
same position.
Rebound Damping Adjustment
The fork rebound damping adjuster has 16 clicks
or more. Turning the rebound damping adjuster
screw (2) one full turn clockwise advances the
adjuster 4 clicks. To adjust the rebound damping to
the standard setting, proceed as follows:
Turn the adjuster clockwise (harder) until it will no
longer turn (lightly seats). Turn the adjuster
counterclockwise (softer) until it clicks. This click
is position 1.
(CRF250R)
The standard position is 11 clicks.
(CRF250RX)
The standard position is 15 clicks.
Make sure that both fork legs are adjusted to the
same position.
NOTICE
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 compression and rebound
damping adjusters are firmly located in a detent,
and not between positions.
Both compression and rebound damping can be
increased by turning the adjuster clockwise.
The fork springs in CRF’s are about right for riders
weighing between 170 lb (77 kg) and 200 lb (91
kg) (less riding gear). So if you’re a heavier rider,
you have to go up on the oil capacity or get a stiff
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 stiff on big bumps, turn the damping
adjuster counterclockwise 1-click and lower the oil
capacity in increments of 0.2 US oz (5 cm
3
) in both
fork legs until the desired performance is obtained.
Do not, however, lower the oil capacity below the
minimum oil capacity.
Minimum oil capacity (CRF250R):
Minimum oil capacity (CRF250RX):
When adjusting oil capacity, bear in mind that the
air in the fork will increase in pressure while
riding; therefore, the higher the oil capacity, the
higher the eventual pressure of any air in the fork.
