Damping: Resistance to velocity of suspension 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 (when riding over a bump).
Rebound: The suspension is rebounding when it is moving back from being compressed (rebounding to the road surface after a bump).
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.
Before evaluating and adjusting suspension settings, check the motorcycle's tires. They must be in good condition and properly inflated. Refer to Specifications → Specifications → Tires: Early Production and Specifications → Specifications → Tires: Late Production.
