Pair Of YSS Progressive Fork Springs [PR375I085-095S285X]

YSS Progressive Fork Springs

YSS progressive fork springs – more precise handling and more comfort.
The progressive fork springs from YSS are the ideal solution for anyone who wants to improve the response of their telescopic fork and at the same time enjoy more stability and comfort on the road or during sporty riding.

High-quality silicon spring steel.
YSS uses high-quality silicon spring steel in its production. This enables a lower wire thickness, which means that the spring works more actively and is slimmer at the same time. Despite the slim design, torsion of the spring is effectively prevented – for precise and controlled spring compression.

Perfect surface for optimum function.
To minimize noise and improve the oil flow in the fork, the springs are completely polished and precisely ground at the top and bottom. This ensures a smoother ride and uniform damping properties throughout the entire suspension travel.

Product features:
– Progressive spring rate – soft in the initial range, firm under load
– Excellent riding stability and reduced dive under braking
– Silicon spring steel – active, slim and torsion-free
– Polished and ground ends – quiet and efficient oil flow
– Made by YSS – known for durable and high-performance suspension components
– Easy to retrofit – suitable for many models
