Considering America's well-known love affair with custom motorcycles, you might think that the Official World Championship of Custom Bike Building would be dominated by U.S.-based builders. Interestingly, though, this year marks the first time the top prize has been won by an American, in this case Dave Cook of Cook Custom Choppers in Milwaukee, Wisconsin.
The winning bike is called Rambler, and it's definitely not the typical custom Harley. In fact, it's not even powered by a V-twin engine. Instead, an air-cooled 550cc four-cylinder engine from International sends power through a modified BMW gearbox and shaft drive to the 21-inch rear wheel.
