Curtiss V8

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. 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
