Wilbers Fork Spring - Zero friction - Progressive YSS these twin shocks are built

these twin shocks are built to soak up harsh landings

we use a linear spring rate and a precisely tuned damping setup

20mm diameter pistons with expanded oil passages

We also sensibly correct chassis geometry via negative travel

high-capacity mono shock engineered for sport bikes

Wilbers Fork Spring - Zero friction - Progressive YSS these twin shocks are builtWilbers progressive fork springs ZERO Friction finishing Our vibratory finishing process (trough vibrator with tailored media) micro polishes the spring surface. The resulting fine, shiny finish reduces surface roughness and friction hence ZERO Friction. Pair with our specially formulated Wilbers fork oil and the specified air chamber for your vehicle to maximize performance. Product may differ from the picture. Recommended viscosity and air chamber:
