Honda CBR600RR 2007 Owner's Manual page 130

Lower spring pre-load and softer damping
provide a softer ride and are usually
preferred for light loads and smooth roads.
Higher spring pre-load and firmer
damping provide a firmer ride and are
recommended for heavy loads, rough road
conditions, and faster, more challenging
riding.
Front Suspension Adjustment
The front suspension can be adjusted for
rider (and passenger) weight and riding
conditions by changing the spring pre-load
and rebound and compression damping.
To adjust, use an appropriate tool or see
your Honda dealer.
