when was the first harley davidson bike built
Harley-Davidson 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.[10][11] Most of the major parts, however, were made elsewhere, including some probably fabricated at the West Milwaukee railshops where oldest brother William A. Davidson was then toolroom foreman. This prototype machine was functional by September 8, 1904, when it competed in a Milwaukee motorcycle race held at State Fair Park. It was ridden by Edward Hildebrand and placed fourth. This is the first documented appearance of a Harley-Davidson motorcycle in the historical record.[10]
Harley-Davidson Twin Cam engine The engine design differed considerably from its predecessor the "Evo" although it shared some design elements with the Sportster line. The 88 represents the displacement in cubic inches of the standard engine. The bore is 95.3 mm (3.75 in) and the stroke is 101.6 mm (4.00 in), meaning the displacement is 88 cu in (1,450 cc). The Twin Cam 96 displaces 96.7 cu in (1,584 cc). The company released 103 cu in (1,690 cc) for 2010 Electra Glide Ultra Limited models, and later for 2012 Softail models and 110 cu in (1,801 cc) for Screamin' Eagle/CVO Models.
