Harley-Davidson, Inc. needs no introduction as an iconic American motorcycle manufacturer headquartered
in Milwaukee, Wisconsin. In 1901, William S. Harley, Arthur Davidson, and brother Walter Davidson began work
on their first motorcycle engine. Their first attempt may have been a failure, but they founded
Harley-Davidson in 1903 and became one of the largest motorcycle manufacturers by 1920. They produced
motorcycles for the United States used in both World War I and II and were one of only two major motorcycle
manufacturers to survive the Great Depression. In fact, they’ve survived numerous changes to ownership and
restructuring, intense global competition, charges of restrictive practices, claims of stock price manipulation, and a
constantly evolving view of the company and bikers. Still, they are widely known for their loyal following and now
manufacture in Pennsylvania, Wisconsin, Brazil, and Thailand. Their classic cruiser style, including high
handlebars, low seats, and chrome parts, is easily recognizable. They’re also noted for their customizability, giving
rise to the chopper style of motorcycle, and for the distinct sound of HD’s powerful engines.
The 1958 Harley-Davidson Sportster is iconic for splitting into two distinct models: the road-going XLH and the
competition-focused, stripped-down XLCH. “CH” stood for “Competition Hot” and was built for performance. It featured a
magneto ignition, larger ports and valves, high-domed pistons, and no battery. Similar to British motorcycles of
the time, the original Sportster line featured the gear-shift lever on the right side and the rear brake on the
left. It was powered by Harley’s early 55-cubic-inch (883cc) overhead-valve Ironhead V-twin engine. It also utilized an
early, distinct form of the famous “peanut” fuel tank that became a hallmark of Sportster styling. In 1958,
Harley-Davidson integrated the camshaft gears directly with the camshafts (eliminating the need for a Woodruff key)
and enlarged the drive and second gears for added durability.
Original, period-correct 1957 XL Sportsters command a premium due to their historical significance, and vehicles
available for sale are quite rare. This 1958 Harley-Davidson Sportster XLCH has undergone a recent complete
restoration and is currently in excellent running condition.
