YSS SUSPENSION Progressive fork spring 7430980

YSS progressive coil fork springs with a firmer design than stock.

YSS fork springs are made from high quality silicon spring steel. This makes it possible to reduce the thickness of the wire, which makes the spring more active and thinner, but at the same time effectively prevents twisting of the spring.

To minimize noise and improve oil flow in the fork, the springs are fully polished and ground on the top and bottom.

The scope of delivery includes 2 springs for a complete conversion of the fork.
