1934 NSU 201 OSL Technical Analysis & Specification Breakdown

Positioned in NSU's sport motorcycle lineup, the 1934 NSU 201 OSL features a 198 cc (12.1 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 8 HP (5.8 kW) at 4,100 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 40.4 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.

On the scales, the 201 OSL measures 120 kg (265 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (15 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,285 mm (50.6 in) wheelbase engineered for quick, flickable steering geometry. The 11.5-liter (3 US gal) fuel tank paired with a rated consumption of 2.3 L/100 km provides an estimated theoretical range of roughly 500 km (311 miles) between fill-ups, while factory top speed is listed at 90 km/h (56 mph).
