YSS Voorvorkveren

The progressively wound fork springs from YSS offer a firmer set-up than the original.
Made from high-quality silicon spring steel, they enable a reduced wire thickness, making the spring more agile and slimmer without losing stability. At the same time, unwanted torsion of the spring is effectively prevented.
To optimise the oil flow in the fork and reduce noise, the springs are fully polished and precision-ground at both ends.
The scope of delivery includes two springs for a complete fork conversion.
