'Through the years of boom and bust Harley Davidson was known exclusively as the builder of large, air-cooled V-twin engines, powering mostly large, heavyweight motorcycles'. (Rafferty, p.8) Harley still remains the foundation of motorcycles today. The first prototype Harley-Davidson was developed in 1901 by both William S. Harley and Arthur Davidson. Throughout their years of building different models they worked on improving the Harley piece by piece and came out with a bike that stood out for it's safety measures and advances. Harley Davidson was also known for its powerful V-twin engine which appeared in 1909. Their first attempt at developing the engine was unsuccessful, but after undergoing revisions in the design it reappeared in 1911. Its new engine was more suitable for the use of a sidecar because it produced more power. The sidecar was used mainly for carrying the wife and family and required the extra horsepower from the engine. 'The tempo of the company picked up until in 1918, when orders were helped by the military, Harley-Davidson was the world's largest motorcycle company.'

The developer's opinions changed when they saw that money could be made and that their motorcycle was one of the top-of-the-line bikes on the market for this kind of use. Many private Harley owners that raced found the motorcycle to hold up well on the track. Once the Harley manufacturers found out about this they started to construct a more advanced motorcycle for racing. By doing this they changed the V-twin style engine to a 37-cubic-inch sports model.
