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]
Rolls-Royce Limited Aero-engine manufacture began in 1914 because the government requested it.[3] Rolls-Royce's Eagle, the first example was made in 1915, was the first engine to make a non-stop trans-Atlantic crossing by aeroplane when in June 1919 two Eagles powered the converted Vickers Vimy bomber on the transatlantic flight of Alcock and Brown.
