An OHV engine resulting from the NSU design effort was decided to be tried out on racing models, in engines with 200, 250, 350 and 500 cc capacity.
Finally, model 601 OSL was produced by 1938, having an OHV, 562-cc engine with 20 h.p. at 3800 rpm. The “OSL” abbreviation meant “overhead, racing, luxus-class.” The look of the motorcycle was magnificent indeed, what with aluminum cylinder and chrome-plated tail pipes.
Model 601 OSL was adopted by the Wehrmacht. The military version of this model was featuring a second seat, large pouches, and an exhaust system painted black. In the army the motorcycle was used as a transportation means for couriers and orderlies, which was only to be expected taking into account its maximum speed of 100 km/h.
In 1939 the production of model 601 OSL was terminated.
