YSS Progressive Rate Springs – High-performance springs for optimised chassis dynamics
The YSS progressively wound fork springs provide a firmer setup than the standard springs, significantly improving suspension performance. These springs are made from high-quality silicon spring steel, which allows for a reduction in wire thickness. The result is an active, slimmer spring that also ensures effective torsion damping.
To minimise noise and optimise oil flow within the fork, the springs are completely polished and
