Motul Light Factory Line Fork Oil 5W

The Motul Light Factory Line Fork Oil 5W is a 100% synthetic ester fork oil built to work across conventional forks, upside-down forks, cartridge-type forks, and rear shocks, giving it a broad range of suspension applications. Motul formulates it with a strong additive package that resists foaming, a special seal conditioner, and high levels of friction modifiers so sliders move freely without unwanted friction. Its high viscosity index helps the oil maintain consistent behavior as temperatures rise, reducing the performance fade that thinner or lower-quality oils can develop under heat.

This oil is rated 5W, a single-grade fork oil where the weight directly sets damping feel. Heavier weights slow the damping action; lighter weights like this 5W allow faster damping response. Match the weight to whatever your service manual specifies for your forks or rear shock. One useful feature is that this oil can be blended with other weights in the Factory Line range to fine-tune viscosity if your manual calls for something between standard grades.
