Putoline HPX R 5W Fork Oil – 1ltr is an advanced synthetic motorcycle suspension fluid developed for precise damping, smooth fork movement and predictable handling. Its lightweight 5W viscosity supports responsive compression and rebound action, making it suitable for compatible road, racing and off-road suspension systems.
The highly refined synthetic base oils and advanced additives help maintain stable viscosity across changing temperatures. The formulation also protects internal fork components against corrosion, oxidation, seal leakage and foaming during demanding riding conditions.
This 5W motorcycle fork oil is suitable for compatible motocross, enduro, trail, road and competition motorcycles. Always confirm the recommended viscosity, filling quantity and fork air gap in the motorcycle or suspension manufacturer’s service manual before use.
