PROGRESSIVE SUSPENSION – Manufacturer Ref: 11-1521

Replacement front fork springs designed for road and touring use. The progressive wound springs provide a soft initial response for comfort in urban and road use, then an increasing stiffness to limit bottoming out under compression. Ideal for maintaining the original geometry of the motorcycle while optimizing fork behaviour under variable loads and large travel.
