Harley Davidson: historic motorcycle manufacturer

Harley-Davidson takeover lovers

Think of a motorcycle manufacturer and chances are Harley-Davidson comes to mind. From humble roots to becoming one of America’s most iconic brands, join Custom Lids, retailer of Bell motorcycle helmets, as they delve into some of the key moments in the rich history of the world’s best-loved biking brand:


The story begins in 1901, when William S. Harley — one of the brand’s founding fathers — drew up a blueprint of an engine that can fit into a bicycle. Designed for use on a regular bicycle, the engine would offer a displacement of 7.07 cubic inches and four-inch flywheels.Harley and the Davidsons on Discovery Channel

While variants of the motorcycle existed prior to this point, it was certainly an important moment in biking history, giving rise to what would become one of the world’s biggest motorcycle manufacturers.


In 1903, the world got one step closer to Harley-Davidson as we know it today. William and his friend Arthur Davidson decided to work together to make the blueprints a reality and manufacture a motorcycle.

Unlike the futuristic production lines of our times, the very first Harley was built in a 10ft by 15ft wooden shed. The first Harley Davidson motorcycle the public could get their hands on was designed to race, with a 3-1/8 inch bore and 3-1/2 inch stroke. One of their first customers was an old school friend, who bought his bike direct.


Just one year later and Harley-Davidson’s success began to snowball. The first Harley-Davidson Dealer, C.H. Lang of Chicago, is established and sells the first three of the brand’s production motorcycles ever made.


As well as their size, the performance of their motorcycles started to make headlines in 1905. July 4th saw one of the brand’s bikes win a 15-mile race in Chicago.


The first V-twin powered Harley-Davidson motorcycle is introduced, offering displacement of 49.5 cubic inches and a horsepower of seven. The cylinders were arranged in a 45-degree layout — a now iconic feature of motorcycles.

By 1920, Harley is the largest motorcycle manufacturer in the world, with 2,000 dealers in 67 countries around the world.


In 1925, gas tanks were modified to have a distinct tear-drop gas tank, which would go on to become one of the bikes’ most iconic features.

By 1931, Harley-Davidson’s superior quality motorcycles, class-leading innovation and exceptional sporting performance had seen off all other American brands expect Indian (Hendee Manufacturing). The pair would remain the only two American motorcycle manufacturers for more than 20 years to come.


A reaction to the Great Depression, all Harley-Davidson gas tanks are painted with a now-iconic eagle design, which triggered the start of graphic design on the bikes.


In 1941, America and the rest of the world was rocked by World War II, with the production of military bikes now taking priority over civilians’. Over the coming years, Harley-Davidson dedicates their business and manufacturing to supporting the US war efforts. Activities included:

  • 1941 — Service School converted to aid the training of military mechanics.
  • 1942 — XA750 bike was produced, designed for desert use although the contract was terminated early when war combat moved away from North Africa.
  • 1943 — Wins the first of four Army-Navy “E” Awards for excellence.
  • 1945 — Over 60,000 WLA models were produced during the war. After the war ends, civilian bike production resumed in November.harley-Davidson WLA in Harley museum
