Definition: Harley-Davidson (1850–1932) was an American motorcycle manufacturer that specialized in two-stroke, single-cylinder, fixed-valve carbureted motorcycles and scooters from its inception until 1932. The company's name is derived from Harley Davidson, the nickname of the company founder. The Harley-Davidson brand has a long history dating back to 1850 when David Sabin founded the Sabin Manufacturing Company in St. Louis, Missouri, where he developed and refined his first motorcycle, the Harleys, which he named the "Caveman." In the early 19th century, Harley Davidson began to produce models like the Harley-Davidson, the Harley, the Chopper, and the King. Harley-Davidson's motorcycles were designed for both practicality and performance. The company's first production model was the Harleys, which featured a streamlined design that emphasized comfort and efficiency. The Harleys are characterized by their comfortable seats, adjustable seat cushions, and soft seats with leather or vinyl upholstery. They also feature sturdy frames, quick-folding handles, and gas-boosting systems. Harley-Davidson's scooters were designed to be lightweight, efficient, and aerodynamic. These motorcycles had a distinctive design that included twin front wheels, narrow, low-profile frames, and an open seat. The scooters were often equipped with adjustable suspension, gas-boosting systems, and adjustable brake calipers. In 1932, Harley-Davidson officially became known as the Harley-Davidson Motor Company. The company's iconic design and marketing efforts led to a significant increase in sales and brand recognition. Harley-Davidson motorcycles were also popular among country folk and law enforcement officials, particularly those from the Great Depression. Today, Harley-Davidson motorcycles continue to be produced by their original factory in St. Louis, Missouri, but are distributed globally through authorized Harley-Davidson dealerships and online stores. The brand remains a symbol of American engineering and innovation.
