There seems to be a lot of discussions about what is the fastest motorcycle in the world, but actually there is not that much to discuss.
The Dodge Tomahawk might be a concept model, but it is almost twice as fast as the second fastest motorcycle in the world (Ducati Desmosedici RR).
The Dodge Tomahawk is powered by a V10 engine from a Dodge Viper sportscar. The engine gives it 500 hp (373 kw) and a supposed topspeed around 675 km/h (420 mph)!
Problem is that the Tomahawk isn’t street legal and that the 10 hand-built versions were sold for no less than $550,000 each
