Rear Suspension Adjustment
Adjustments for Type of Track
Hard-surfaced track Begin with the standard settings. If the suspension is too stiff/soft, adjust according to the chart below.
Sand track Lower the rear end (to improve front wheel stability) by increasing Race Sag (reduce spring pre-load).
Example: – Turn the compression damping adjuster and, especially, rebound damping adjuster to a stiffer setting.
– Increase standard Race Sag (+0.2 to 0.4 in/5 to 10 mm).
Mud track Adjust to a stiffer position because mud build-up increases your CRF’s weight.
Example: – Adjust the compression and rebound damping adjusters to stiffer settings.
– Install the optional stiff spring.
– Reduce standard Race Sag (–0.2 to 0.4 in/5 to 10 mm).
Adjustments for Too Soft/Stiff Suspension
Symptom Action
Stiff suspension Entire travel too stiff – Test softer compression and rebound damping adjustments in 1/4 turn increments.
– Install the optional soft spring.
Soft suspension Suspension bottoms or rear end
shakes:
– Test stiffer compression and rebound damping adjustments in 1/4 turn increments.
– Install the optional stiff spring.
Adjustments for Too Soft/Stiff Suspension
Symptom Action
Rear end kicks up on deep bumps on sand track. – Test stiffer compression and rebound damping adjustments in 1/4 turn increments until the rear end does not
kick up and/or the suspension becomes stiff.
– Then test softer compression damping adjustments in 1/4 turn increments.
Suspension bottoms and rear end kicks up on large bumps
on a hard-surface track.
– Test stiffer compression and rebound damping adjustments in 1/4 turn increments.
Rear end gets poor traction accelerating away from a corner. – Test softer rebound damping adjustments in 1/4 turn increments. (Test no more than 3 turns.)
– If 1/2 or 3/4 turns don’t produce satisfactory results, test softer compression damping adjustments in 1/4 turn
increments.
– After the above adjustment, check if the suspension bottoms after jumping. If it does, test stiffer compression
damping adjustments in 1/4 turn increments.
Rear end kicks sideways and suspension feels stiff on
continuous bumps.
– Test softer rebound damping adjustments in 1/4 turn increments.
– After the above adjustment, check if the suspension bottoms after jumping. If it does, test stiffer compression
damping adjustments in 1/4 turn increments.
