Suspension Adjustment Guidelines - Honda CRF450R Owner's Manual

SUSPENSION ADJUSTMENT GUIDELINES

Follow the procedures described below to accurately adjust your CRF using the methods described on pages 72 – 89. Remember to make all adjustments in one-clik
increments. Test ride after each adjustment.

Mud track
Adjustments for Too Soft/Stiff Damping
Soft Initial travel too soft:
suspension • Steering is too quick
• Front end darts while cornering or riding in a straight line.
Middle travel too soft:
• Front end dives when cornering.
Final travel too soft:
• Bottoms on landings.
• Bottoms on large bumps, especialy downhill bumps.
Entire travel too soft:
• Front end shakes.
• Fork bottoms over any type of terrain.
Begin with the standard setting. If the suspension is too stiff/soft, adjust according to the chart below.
Adjust to a stiffer position.
Example: – Turn the compression damping adjuster to a stiffer position.
– Install the optional stiff spring. (Adjust compression damping to a softer position and rebound damping to harder
position at this time.
Adjust to a stiffer position because mud build-up increases your CRF's weight
Example: – Turn the compression damping adjuster to a stiffer setting.
– Install the optional stiff spring.
Sympton
– Test stiffer compression damping adjustments in one-click increments.
– Test stiffer rebound damping adjustments in one-click increments.
If suspension isn't stiff in initial travel:
– Test stiffer compression damping adjustments in one-click increments.
If initial travel becomes stiff because of the above adjustment:
– Reduse the rebound damping in one-click increments.
– Test softer compression damping adjustments in one-click increments.
If that doesn't solve the problem, install the optional stiff spring.
If intial and middle travel are not stiff:
– Test stiffer compression damping adjustments in one-click increments.
If initial and middle travel is stiff:
– Install the optional stiff spring
If initial travel is stiff after installing the optional stiff spring:
– Test softer compression damping adjustments in one-click increments.
If initial travel is still soft after installing the optional stiff spring:
– Test stiffener compression damping adjustments in one-click increments.
If final travel is still soft after installing the optional stiff spring:
– Increase the fork oil capacity in increments of 0.2 oz (5 cc).
– Install the optional stiff spring.
– Test stiffer compression damping adjustments in one-click increments.
– Increse rebound damping in one-click increments.
