Transforming Your Husqvarna Handling On and Off-Road medium.com
The tuning process rests on three fundamental adjustments: spring preload, compression damping, and rebound damping. Spring preload does not change the spring’s stiffness; it adjusts how much the spring is already compressed when the bike is at rest, setting the correct race sag. This is your starting point. For optimal handling, you typically aim for a sag measurement of 30–35% of the suspension’s total travel. Incorrect sag — whether the bike sits too high (too little preload) or wallows low (too much preload) — dramatically upsets geometry and reduces available travel. Once sag is set, you fine-tune damping, the force that controls the speed of the suspension’s movement. Compression damping governs how fast the suspension compresses over bumps. Too stiff, and the bike will deflect and feel harsh; too soft, and it will dive or bottom out. Rebound damping controls how fast the suspension returns after being compressed. Too fast, and the bike will pogo or feel unstable; too slow, and it will “pack down,” not recovering in time for the next impact.
