The working principle of a typical motorcycle fork has much in common with that of an automotive strut – both of these parts use a coil spring and special oil to absorb bumps and cushion the suspension's movement. However, their construction is different. In most cars, shock absorbers are unrepairable and work until the oil starts leaking out through deteriorated seals. Motorcycle forks typically have a long spring inside, which contracts and rebounds on road irregularities, while fork oil provides the necessary rebound damping and lubricates some of the internal components.
Actually, fork oil largely acts as a hydraulic fluid. It has two crucial parameters which influence suspension performance – its viscosity and quantity in a fork or rear shock. They are selected according to the bike's weight and expected loads and are usually stated in the manufacturer's specifications. In general, the thicker the oil is, the stiffer the suspension gets, which also makes it more capable under high stresses. Of course, changing viscosity alone will not do wonders, but the difference in stiffness is rather notable.
Besides, some fork oils meant for racing use a synthetic base and better withstand heat, i.e. their thickness remains more stable during off-road racing when fork temperature is high enough. Over time, suspension oil deteriorates and gets contaminated with dirt or small metal particles. Besides, damaged seals can be the reason for oil leaks or water getting inside the fork, which may result in its breakdown. Fork oil change is a common servicing procedure whose approximate intervals are defined by the motorcycle manufacturer and type of use. This can be done once a year or more often if needed. On our virtual shelves, you can find a wide range of suspension oils meant for different riding conditions and motorcycles including lightweight dirt bikes, heavy cruisers, dual-sport bikes, and so on.
