Harley-Davidson (HD) är ett amerikanskt
motorcykelfabrikat grundat 1903 av William
Harley och bröderna Walter, William och
Arthur Davidson i Milwaukee i Wisconsin.

En unik och typisk detalj i Harley-Davidsons
motorer är "the V-twin" med kort vevaxel.
Cylindervinkeln är ofta 45 grader och
vevaxeln har bara en vevtapp. Båda
vevstakarna drivs därmed från samma punkt
på vevaxeln. Resultatet blir en ojämn eller
haltande tändföljd. Jämfört med en 0 graders
radmotor som får en naturligt jämn tändföljd
så får Harley-Davidson motorn på detta sätt
sin karaktär vad beträffar ljud och vibrationer.
11. The company has survived numerous ownership arrangements, subsidiary
arrangements, periods of poor economic health and product quality, and intense
global competition[4] to become one of the world's largest motorcycle manufacturers
and an iconic brand widely known for its loyal following. There are owner clubs and
events worldwide, as well as a company-sponsored, brand-focused museum.
Harley-Davidson is noted for a style of customization that gave rise to the chopper
motorcycle style.[5] The company traditionally marketed heavyweight, air-cooled
cruiser motorcycles with engine displacements greater than 700 cc, but it has
broadened its offerings to include more contemporary VRSC (2002) and middle-
weight Street (2015) platforms.

13. In 1901, 20 year-old William S. Harley drew up plans for a small engine with a
displacement of 7.07 cubic inches (116 cc) and four-inch (102 mm) flywheels[7][8]
designed for use in a regular pedal-bicycle frame. Over the next two years, he and his
childhood friend Arthur Davidson worked on their motor-bicycle using the northside
Milwaukee machine shop at the home of their friend Henry Melk. It was finished in
1903 with the help of Arthur's brother Walter Davidson. Upon testing their power-
cycle, Harley and the Davidson brothers found it unable to climb the hills around
Milwaukee without pedal assistance, and they wrote off their first motor-bicycle as a
valuable learning experiment. The prototype of the new loop-frame Harley-Davidson
was assembled in a 10 ft × 15 ft (3.0 m × 4.6 m) shed in the Davidson family
backyard.
