1954 NSU 101 OSB Technical Analysis & Specification Breakdown

Engineered by NSU for the sport motorcycle segment, the 1954 NSU 101 OSB relies on a 98 cc (6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 5.8 HP (4.2 kW) at 6,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 59.2 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
