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)
Before evaluating and adjusting suspension settings, check the motorcycle's tires. Refer to Specifications → Specifications: 2007 Firebolt Models → Tires: 2007 Firebolt Models. They must be in good condition and properly inflated.
