Dodge Tomahawk: World's Fastest Bike

At the 2003 North American International Auto Show in Detroit, Michigan, Dodge unveiled a vehicle with an unusual design, featuring the 500 hp (373 kW) @ 5600 rpm, 8.3 L V10 engine from the Dodge Viper. 10-cylinder 90-degree V-type, liquid-cooled, 505 in³ (8275 cc). The vehicle has two front wheels and two rear wheels, making it a kind of motorized quadricycle rather than a typical motorcycle. Though it has four wheels, to associate the Tomahawk with a quad-type vehicle is not entirely accurate; quad-type vehicles have more in common with the automobile. They turn like an automobile, while the Tomahawk turns by leaning. According to the official specs 0-60 mph times have been estimated at 2.5 seconds, with an estimated top speed of 350 mph. But there are also reports that the top speed is 676 km/h (about 420 mph). While the Tomahawk is not street-legal, it could, theoretically, be ridden.
