YSS Fork spring - BMW / Yamaha

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

The YSS fork springs are made of silicon spring steel. This allows the wire thickness to be reduced, which has a positive effect on the spring properties, but at the same time prevents torsion of the spring.

The spring is supplied ground at the top and bottom.

The scope of delivery includes a pair (2 pieces) of fork springs for both fork legs.
