Troubleshooting Suspension Set-up
• Check fork and rear shock absorber assembly performance.
Confirm that the fork pipe and rod are not bent, If there is such
trouble, modify or exchange the defective part.
• Check to see if the center shifted during tightening of the front
axle shaft and whether the fork has been twisted.
• Lower preload
• Change to a softer spring
• Reduce the amount of oil (front suspension only)
• Increase preload
• Change to stiffer spring
• Increase the amount of oil (front suspension only)
• Reduce the damping force (front: adjuster or oil viscosity.
Rear: adjuster)
• Review the selection, and reduce air pressure
• Shift the resonance point by either increasing or reducing the
preload (be sure to confirm the stroke when doing so).
• Shift resonance point by increasing or decreasing damping
force.
• Check the bolts and bearings to see if they are tight and prop-
erly secured.
• Rebalance and confirm whether or not the rim is deformed.
• Raise or lower the air pressure.
• Lower preload.
• Increase front distribution load (either increase the rear ride
height or front fork projected length).
• Lower preload.
• Change to a softer spring.
Increase preload.
• Change to a stiffer spring.
• Raise rear ride height (with ride height adjuster).
• Increase preload of rear spring.
• Lower preload of front.
• Increase front fork projected length.
• Reduce rear damping force (rebound).
• Increase damping force.
• Either increase or reduce damping force (rebound) to shift res-
onance point. Lower preload.
Symptom Suspected Causes Countermeasures
Bottoming (a solid feeling)
Chattering
Excessive movement of the steering
Does not turn-in easily at corners
Floating feeling
Hopping (rear)
Poor performance
Excessive preload on the spring set
Hitting bottom (full stroke)
Excessive damping force
Excessive tire rigidity
Poor matching between body, suspension and tires
Others
1. Loosening of area adjacent to head pipe and others.
2. Loss of balance or deformation of tire rim.
3. Misselected tire or misadjusted air pressure.
In cases experienced when the throttle is ON: Lack of
rebound stroke (From 1G) of the front fork.
In cases experienced when the throttle is OFF.
1. Insufficient stroke due to excessively stiff proper-
ties of front spring.
2. Excessive stroke due to overly soft spring proper-
ties.
Caster angle is too large
Lack of damping force
Resonance under spring die to inadequate damping
force.
