The fork oil is the oil that goes in the front forks of a motorcycle and acts as the shock absorber.

Fork oil is not the same as engine oil.

Engine oil is mainly used for lubricating and cooling down the engine components. Fork oil, on the other hand, is used as a shock absorber.

Front fork oil in a motorcycle acts as a dampener to the vibrations coming from the front wheel and provides a smooth riding experience to the motorcycle rider.

Fork oils are different in composition from engine or brake oils and use chemicals with anti-friction properties. Several friction modifiers are used to modify lubrication qualities as well.
