Yet another motorcycle manufacturer with its roots in the bicycle industry, NSU built its first powered two-wheeler in 1900. Proprietary engines were used initially, but within a few years NSU was making its own power units and was one of the first manufacturers to fit two-speed transmission. The marque established a strong presence in the UK market, ranking second only to Indian among imported makes prior to WWI. NSU recommenced motorcycle manufacture at the end of The Great War and rapidly returned to full production. In 1929 the German firm succeeded in recruiting designer Walter Moore from Norton. Moore had been responsible for Norton's first successful overhead-camshaft-engined machine, the CS1, so it came as no surprise when distinctly Norton-esque 'cammy' NSU Super Sport models appeared a short time later. In 1932 NSU introduced the Moore-designed 'O' series of overhead-valve singles, which would form the mainstay of production in the mid-1930s. However, it was not for his contribution to the design of its medium and large-capacity four-strokes that NSU had most reason to thank Moore, but for his 98cc two-stroke ultra-lightweight Quick, almost a quarter of a million of which were manufactured between 1936 and 1953.

This project with original paint is well preserved with oil and is perfect for a patina restoration. It spent his whole life in Austria and was delivered to the NSU dealer “Ernst Frey” in Vienna. The dealer transfers are still on the bike. All main parts are on the bike. The toolboxes in the back are original and it comes with a new wiring harness. Aside from the original paint special on the bike is the fact it is first year of production of the 351 OSL Series.
