Rambler by Cook Custom

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.

Features

Frame, front end, controls, sheet metal, lights, brackets, wheel hubs, all brackets/mounts etc. are one-off Cook fabricated (exceptions, carburetor, wheel rims, spokes, tires, brake calipers and master cylinders).
Entire drive line is a combination of extensively modified Honda, BMW, Yamaha donor parts and Cook one-off components (one-offs include Exhaust, Intake Manifold, Timing Cover and assembly, bell housing and clutch assembly, auxiliary oil reservoir, Oil Regulator, lines, etc.)
Hand and foot controls finished in laminated layered exotic hardwoods. Seat upholstery by Rich Phillips. Frame and Front end polished stainless steel with "yellow silver" brazed joints. All remaining "silver" components are polished stainless or nickel plated.
