Article description

Progressively wound fork springs from YSS



The progressive winding of the fork springs ensures a high response of the front fork. At the same time a penetration is prevented under heavy load, since the spring rate increases during immersion. This significantly improves driving behavior and driving safety.



The YSS fork springs are made of silicon spring steel. This can reduce the wire thickness, which has a positive effect on the spring properties, but at the same time avoids torsion of the spring.



The spring is ground at the top and bottom and delivered with a lasered ABE pressure.

The package includes a pair (2 pieces) fork springs for both fork legs.
