<p>During the 1930s and the 1950s NSU of Neckarsulm, Germany was the world’s largest motorcycle manufacturer. Founded in 1873 to make knitting machines, NSU became a revered manufacturer of bicycles (in 1886 under the Germania brand), motorcycles (in 1901) and cars (in 1905) that was eventually gobbled up in 1969 by today’s behemoth Volkswagen Group.</p>
<p>In 1953 NSU launched their remarkably successful series of street (Max) and production race bikes (Sportmax) with its innovative, air-cooled 250cc overhead cam single. The cam drive was unique, using a pair of “connecting rods” from crankshaft to camshaft. Its cylinder is angled forward in a monobloque (unibody) pressed steel frame with a leading link front fork, all of which was created under the guidance of engineering genius Albert Roder. For the Supermax, an aluminum fuel tank and all-enveloping fairing – often known as a dusbin – was fitted to complete this fast, lightweight road racer.</p>

<p>NSU won several speed records in the 1950s, being no stranger to the Bonneville Salt Flats. However, perhaps their best-known machine of all is the NSU Quickly moped, of which&nbsp;more than 1 million were sold. By 1969 it was all over; NSU’s newly found obsession with the Wankel rotary engine had ruined the company.</p>
