Harley-Davidson – Historical Models



This rare example is a 1903 Harley-Davidson single–essentially a bicycle with an engine. It’s what started the company on its 100-year journey through wars, depressions, changes of ownership and the ups and downs of motorcycle racing.




By 1920, Harley was making singles and V-Twins, and this 1920 race bike used two separate camshafts to operate the engine’s overhead intake valves. An earlier model in 1913 sported a double-overhead-cam 4-valve engine





After World War II, the AMA racing rules were changed to bring costs down for all the factory entries. The new law dictated that all race bikes must be based directly on high-volume production machines. This Harley WR 750cc flathead race bike was one result. Note that it has no brakes and no rear suspension

Harley’s first true high-performance street bike was the 1955 KHK, like the one shown here. It featured a larger flathead engine, 54 vs. 45 cu.-in. of displacement, rear suspension, a higher compression ratio and hotter camshafts in order to compete with the BSAs and Triumphs of the day. Two years later, it morphed into the XLCH Sportster 883, that’s still sold today as Harley’s entry-level model.





The Heroes of Harley-Davidson exhibit has only one bike you’re allowed and encouraged to sit on, this 1965 Electra Glide, with electric starting and overhead valves. It started a revolution in Harley’s big-bike designs.







Willie G. Davidson has been in charge of Harley’s design department for more than 30 years, and this was his debut piece–the 1970 Super Glide with its raked front end, fiberglass tailpiece and red, white and blue paint job

Harley-Davidson has made strategic alliances with a number of companies over the years, none better than with Aermacchi of Italy. This company provided Harley with 125, 165, 175 and 250cc race and street bikes from the late 1950s through the mid-Seventies. This is an Aermacchi-based road racer from 1974.

And then there was Robert “Evel” Knievel, the man who pioneered motorcycling’s major-event business and singlehandedly started what became the X Games. This is his XR750 stunt cycle






Cafe racers were popularized by the Brits and the Japanese in the 1970s, and the XLCR Cafe Racer limited-production model was Harley’s offering. It had siamesed exhaust pipes and a coffin-shape tank, and nearly every piece of it was black





World War II saw Harley-Davidson convert for war production, as demonstrated by these two courier bikes. The one on the left is powered by a BMW R32 horizontally opposed flathead Twin engine, the one on the right is all Harley. Founder’s son John E. Harley was the director of motorcycle rider training at Fort Knox during the war.





This collection of early board track Harley racing bikes is purported to be the finest ever assembled. These and the other bikes were secured by the museum’s own assets, from Harley-Davidson’s own collection and from private collectors and other museums around the country
