The company sells heavyweight (over 750 cc) motorcycles designed for cruising on the highway. Harley-Davidson motorcycles (popularly known as "Harleys") have a distinctive design and exhaust note. They are especially 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 with limited success and have largely been abandoned since the 1978 sale of its Italian Aermacchi subsidiary.
Harley-Davidson sustains a loyal brand community which keeps active through clubs, events, and a museum. Licensing of the Harley-Davidson logo accounts for almost 5% of the company's net revenue.
