An oil cooler for a motorcycle includes a heat exchanger residing within a primary drive between an engine pulley and a clutch pulley. A fan within the primary drive pushes or pulls air through the heat exchanger. The fan may be electrically or mechanically operated and mounted to one of a base plate or a cover plate of the primary drive. Alternatively, the fan may be formed as a mechanical portion of one of the primary drive components. Vectoring blades may assist in directing an air flow within the primary drive to the heat exchanger, and vents may be formed in the cover plate for air intake and/or exhaust.Motorcycle Oil Cooler Radiator is made of Aluminum, Steel Wire.Oil cooling is the use of engine oil as a coolant, typically to remove surplus heat from an internal combustion engine. The hot engine transfers heat to the oil which then usually passes through a heat-exchanger, typically a type of radiator known as an oil cooler. The cooled oil flows back into the hot object to cool it continuously.Oil cooling is commonly used to cool high-performance motorcycle engines that are not liquid-cooled. as well as customized motorcycle Oil Cooler for universal models,Yamaha,YBR125 RX115 RX100 DT175 JOG50 BWS100 Honda C70 C90 CG200, Kawasaki,SUZUKI,KTM,Simson, MZ, etc
