Ressorts Fourche Moto YSS PR350I055-085S575-X

Progressively wound fork springs from YSS in a firmer design than the original.

The YSS fork springs are made of high quality silicon spring steel. This allows the wire thickness to be reduced, which makes the spring more active and slimmer, but at the same time effectively prevents torsion of the spring.
To minimize noise and improve oil flow in the fork, the springs are completely polished and ground at the top and bottom.
2 springs are included for a complete fork conversion.
