This NSU is called the Supermax because it was simply a superior 250cc roadster of the 1950s and early ‘60s. NSU built the smoothest, fastest, best-handling and most reliable 250 in the industry by the 1950s, with a unit-construction, 4-speed motor that was virtually unbreakable in a pressed-steel chassis with leading-link forks styled gracefully with deep fenders and rounded chrome fuel tank. Chief NSU engineer Albert Roder designed his own system for driving the rocker gear of the Max series of roadsters, which first appeared in 1952 as the Model 251 OSB Max. Rather than using pushrods or a chain-drive OHC or a shaft-and-bevel OHC, Roder created a unique valve train using a pair of connecting rods running alongside the cylinder that gave positive OHC valve operation he called the Ultramax system. The system proved easy to tune, and the factory offered a Sportmax production racer version of the Max series that shared its pressed-steel chassis and simple single-cylinder motor, at a time when the NSU factory absolutely dominated the 250cc class of the World Championships.

Our NSU Supermax is the less common Blue color, it is unrestored, original paint and upholstery. The chrome is quite good with some light surface rust on the spokes and areas of the rims. The gas tank has a small  1 inch long dent on the left side. The tires are the old German Dunlops that were OEM on this bike. This bike runs and rides perfect. It starts easy and is a joy to ride.  The odometer indicates 13892 miles which is believed to be actual miles. It has been part of the Blue Moon Cycle collection for nearly 20 years and now offered for the first time. Call John for details. 770 447 6945 x 20
