Oil line closure, Motorcycle, Curtiss V-8


As a manufacturer and racer of motorcycles, it was only natural for Curtiss to wonder how fast he could move on a motorcycle with his V-8. He instructed his workers to construct a frame that could support the weight of the engine. The Curtiss V-8 was air-cooled, producing approximately 30 to 40 horsepower at 1,800 rpm. The motorcycle used direct drive because a conventional chain-and-belt transmission could not withstand the power of the massive engine. Curtiss took the motorcycle to the Florida Speed Carnival at Ormond Beach in January 1907. He recorded a record-setting speed of 218 kph (136 mph) during his run. He was dubbed "the fastest man on Earth."
