Factory Fluid StandardDirect Spec

Maxima Racing Fork Fluid 5W (1 Liter)

Formulated with anti-foam agents and shear-stable viscosity index improvers to prevent damping fade under aggressive riding heat.

Fork & Dust Seal KitExact Stanchion Fit

All Balls Racing 46mm Fork & Dust Seal Kit

Features directional triple-lip rubber seal profile and external garter springs engineered to withstand heavy stanchion flex without weeping.

Air-Gap Tuning PhysicsBottoming Control

110 mm (4.33 in) compressed, spring removed

Trapped air column acts as a progressive spring in final 30% of stroke. Adding +5mm oil increases bottoming resistance without stiffening small bump compliance.
