Curtiss V-8 motorcycle

The Curtiss V-8 motorcycle was a 269 cu in (4,410 cc) V8 engine-powered motorcycle designed and built by aviation and motorcycling pioneer Glenn Curtiss that set an unofficial land speed record of 136.36 miles per hour (219.45 km/h) on January 24, 1907.^[6][7] The air-cooled F-head engine was developed for use in dirigibles.^[8][9][10]

Engine

The forty horsepower engine was the two carburetor version of the Curtiss Model B-8 aircraft powerplant, one of thirteen engines listed in the May 1908 "Aerial and Cycle Motors" catalog.^[1] The engine weighed 150 lb (68 kg) and was offered for US$1,200 but it did not sell, in spite of the engine's notoriety from the speed record.^[1] An eight carburetor version of the Model B-8 was used in the experimental AEA Red Wing and White Wing airplanes that flew in 1908.^[1]

Legacy

Curtiss remained "the fastest man in the world," the title the newspapers gave him for going faster than any vehicle, on land, sea or air, until 1911,^[11] when his absolute record was broken by the 141.7 mph (228.0 km/h) Blitzen Benz automobile.^[12] No motorcycle surpassed the record until 1930.^[13][14] Curtiss's success at racing strengthened his reputation as a leading maker of high-performance motorcycles and engines.^[15]

It has been suggested that the literary character Tom Swift was based on Curtiss.^[12][16] Tom Swift and His Motor Cycle, the first of over 100 books in the Tom Swift series, was published shortly after the V-8 record setting run.

The record setting V-8 motorcycle is now in the Smithsonian's National Air and Space Museum.^[17] The Air and Space museum lent it to the Guggenheim for the 1998 The Art of the Motorcycle exhibition in New York.^[9][18]

The Curtiss OX-5 aero engine, a successor of the V-8 motorcycle engine, powered several United States civilian and military aircraft. More than 10,000 were manufactured.^[19]
