Unless you ride a very traditional bicycle, your front fork contains oil. And you may replace the oil on occasion. Motul is a manufacturer for lovers of quality products. Their high quality and high performance products are justifiably used in racing cycles. They are developed with the latest technology and extensively checked to ensure they remain perfect in the most demanding conditions. Motul Factory Line front fork oil is a 100% synthetic fork oil based on Motul technosynthesis, for standard motorcycle forks. This oil has a viscosity of 7.5W. Motul fork oil prevents wear and corrosion, does not attack the seals and improves the damping characteristics of your fork considerably. In standard forks you can mix products (light, medium, medium/heavy and heavy damping) without any problem to create a perfect damping performance. Always use the amount specified by the manufacturer.
