An engine lubrication system commonly used on motorcycles and ATVs. This system is set up so that the bulk of the engine oil is stored in a remote location such as an oil tank or the motorcycle frame itself. The oil is fed into the supply side of the oil pump by gravity and is pumped through the engine and then returned to the oil tank or frame by the return side of the oil pump. Dry sump lubrication systems allow the engine to be placed lower in the frame for a lower center of gravity to improve handling.
