Damping: Resistance to movement. Damping affects how easily the suspension can move and limits oscillations of the system once movement has begun.
Compression: The suspension is compressed when the wheel moves upward.
Rebound: The suspension is rebounding when it is moving back from being compressed.
Vehicle Sag: The amount the rear shock and fork springs are compressed by the weight of the motorcycle.
Rider Sag: The amount the rear shock and fork springs are compressed by the weight of the rider on the motorcycle.
Preload: An adjustment made to the rear shock and front fork springs to limit vehicle and rider sag to a standard percentage of total suspension travel.
NOTICE
Compression and rebound adjusting valves may be damaged if too much force is used at either end of the adjustment range. (00237a)
