Harley-Davidson, Inc (NYSE: HOG, formerly HDI), often abbreviated H-D or Harley, is an American motorcycle manufacturer. Founded in Milwaukee, Wisconsin, during the first decade of the 20th century, it was one of two major American motorcycle manufacturers to survive the Great Depression. Harley-Davidson also survived a period of poor quality control and competition from Japanese manufacturers.
The company sells today only heavyweight motorcycles with over 700 cc, designed for cruising on highways. Harley-Davidson motorcycles, or "Harleys", are noted for the tradition of heavy customization that gave rise to the chopper style of motorcycle. Except for the modern VRSC model family, current Harley-Davidson motorcycles reflect the styles of classic Harley designs. Harley-Davidson's attempts to establish itself in the light motorcycle market have met little success and have largely been abandoned since the 1978 sale of its Italian Aermacchi subsidiary.
Harley-Davidson sustains a large brand community which keeps active through clubs, events, and a museum.
