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 & 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.
In the 1960s, Harley-Davidson motorcycles were a prominent force in drag racing. These
bikes, often modified Sportsters, gained popularity for their powerful engines and competitive
performance. The motorcycles were known for their single-engine, carbureted setups and, in the
Top Fuel class, the use of nitromethane, which provided significantly more power than gasoline. Some
riders pushed the boundaries of speed and performance with innovative modifications. Racers often
lightened their motorcycles, incorporating features like lightweight aluminum rims, modified
transmissions, and custom tires.
The Harley-Davidson brand dominated the Top Fuel and "no-bar" drag racing classes. In the
1960s, the Top Fuel motorcycle class was a relatively new and evolving category, though other
brands also saw experimentation with nitromethane fuel. The "no-bar" style, where bikes raced
without wheelie bars—safety devices designed by Carl McClanahan that prevented the
motorcycle from lifting too high—was a popular style of drag racing with roots tracing
back to Harley-Davidson’s early days. In the late 1960s, riders like Joe Smith and Gordon
Kately achieved significant success with modified Sportsters, including multiple wins at the NHRA
U.S. Nationals.
Carl McClanahan, a prominent drag racer, author, and inventor, started drag racing in 1958 on a 1951
74-inch Harley-Davidson Panhead. Since then, he collected record after record, trophy after
trophy, and first place after first place. His bikes excelled because of the skills, techniques, and
tricks he had learned over years of tinkering. He reports that he built the first set of
motorcycle wheelie bars. He also built what may have been the first twin-engine Sportster using
a pair of 66-inch engines in line, falling off during four of the first seven outings on the
contraption before disassembling it. His genius inspired a generation with his book,
V-Twin Thunder!
A Handbook of Inexpensive Performance Modifications for Harley-Davidson Motorcycles.
Among the records he has set and held are:
- 1963: Alton, IL. 11.75 seconds, 123.288 mph on a 66 inch Sportster with a lay down frame.
This bike ran 11.55, 125 mph later in 1963.
- 1969: Alton, IL. AHRA world record A/fuel: 9.57 on an 89 inch Sportster in a Yetman frame.
This bike later ran consistent 9.30s to 9.40s.

This original 1965 Harley-Davidson Sportster XLCH KHK Frame Custom Engine Dragster was
built and raced by legendary drag racer Carl McClanahan. The engine, a 55 cu. in. S&S V-twin, has
been rebuilt and is in good running condition, and sports the number 65XLCH5343. The tank displays
the phrase “Belly Burner,” a nickname given to low-slung, stretched-chassis drag bikes
that placed the rider in a nearly prone position over the engine. “NHRA Record” and
“IHRA Record” have been painted on the tank, a celebration of the accomplishments of
McClanahan with the National Hot Rod Association and International Hot Rod Association. The
motorcycle appears to have been raced with The Drag Racers Association/Midwest Owners & Drivers
Association in the A B class. It also sports the emblem of Custom Engines, McClanahan’s
company, where “Carl’s Harleys Take the Worry Out of Being Close.”
