Progressive fork spring YSS for BMW R100GS R 100 GS

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

The YSS fork springs are made from high-quality silicon spring steel. This allows for a reduction in wire thickness, making the spring more active and slimmer, while effectively preventing torsion of the spring.
To minimize noise and improve oil flow in the fork, the springs are fully polished and ground at both the top and bottom.
The delivery includes 2 springs for a complete fork conversion.
