YSS SUSPENSION fork spring LINEAR 4.9 (2U) 743.03.78

YSS linear fork springs with a firmer design than the 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 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.
