PD335-D1 - Adapter Size = OD: 33.5mm Step: 23.9mm H: 7mm (Refer to main image)

Upgrade your suspension with YSS PD (Progressive Damping) Valves, engineered to bring modern cartridge-style performance to conventional telescopic forks. Developed as a smart, cost-effective solution, PD Valves transform fork response, giving you smoother damping and more predictable control across all riding conditions.

 

By regulating oil flow dynamically, the Progressive Damping system reduces harshness, improves stability, and delivers a more planted front end. The result is less dive under braking, better corner entry confidence, and enhanced grip over rough or uneven surfaces.

 

Designed for straightforward installation, YSS PD Valves are tuned and work seamlessly for spirited road riding to track day fun, they provide an affordable performance upgrade that riders feel instantly.
