Introduced in 1952, the Max was a technical revolution in the European motorcycling scene. Its 247 cc single-cylinder four-stroke engine, increased to 251 cc in the OSB version, is driven by a remarkably ingenious connecting rod and lever valve system, designed by engineer Albert Roder to replace the conventional overhead camshaft with a lighter and more compact solution. A mechanism of absolute mechanical elegance, patented by NSU and jealously guarded, which gives the engine a smoothness and precision unrivalled in its class.
A motorcycle that fully embraces its modernity at a time when most of its contemporaries still shamelessly expose their mechanics. The telescopic front fork suspension and rear swingarm complete a design of remarkable coherence and maturity for the era.
1956 was one of NSU’s final glorious years in motorcycling; the company was preparing to gradually phase out motorcycles to focus on cars, and the Max models of this generation are among the last expressions of a level of craftsmanship that would never be equalled. A model from this year is therefore a precious testament to a glorious twilight.
