Silkolene RSF 15w Semi-Synthetic Fork Oil.
Advanced synthetic-base suspension fluid designed for the latest road and competition suspension systems. Integrated with low friction synthetics, anti-foam and wear-resistant additives to ensure predictable suspension performance, long seal life and smooth action.
The RSF range provides consistent damping performance throughout the operating range, due to the fact the viscosity changes less with increasing temperature.
Used extensively as Original Equipment in many modern motorcycles.
