YSS progressively wound fork springs in a firmer design than original.YSS fork springs are made of high quality silicon spring steel. This allows the thickness of the wire to be reduced, which makes the spring more active and thinner, but at the same time effectively prevents the spring from twisting. To minimize noise and improve oil flow in the fork, the springs are fully polished and ground on the top and bottom. The delivery includes 2 springs for a complete fork conversion.
