Harley-Davidson's official name for the engine was likely related to the company's attempt to reform its image following the 1981 management buyout from previous owner American Machine and Foundry (AMF). [2] Both the heads and cylinders of the Evolution engine are made from aluminum to reduce weight compared to a cast iron design.
