1931
The NSU 351 TS, released in 1931, represented NSU's entry into the competitive mid-size motorcycle market of the era. Building upon previous NSU models, it offered a refined package aimed at riders seeking a reliable and capable machine. Direct competitors included models like the BMW R2, offering similar displacement and features in the German market.
At the heart of the NSU 351 TS lies a 346.0 ccm (21.11 cubic inches) single-cylinder, four-stroke engine. This powerplant allowed the motorcycle to reach a top speed of 100.0 km/h (62.1 mph), sufficient for the roads of the time. The bike's weight of 130.0 kg (286.6 pounds) contributed to its manageable handling. With a fuel capacity of 10.00 litres (2.64 US gallons), the 351 TS provided a reasonable range for longer journeys.
Riding the NSU 351 TS offered a characterful experience. With its upright riding position, it was more suited for daily commuting than long tours. The suspension, typical of the era, provided a comfortable ride on well-maintained roads, but could become jarring on rougher surfaces. The single-cylinder engine's thrum offered a distinctive soundtrack, contributing to the overall riding experience.
The NSU 351 TS appealed to a wide range of riders in 1931, including those seeking a dependable machine for daily transportation and weekend excursions. Its blend of performance and practicality made it a popular choice. While not the fastest or most luxurious motorcycle available, the 351 TS provided good value and reliable transportation in a visually appealing package.

• Limited top speed and acceleration compared to later models, making it unsuitable for modern high-speed traffic. • The rigid frame and basic suspension system provide a harsh ride, lacking the comfort of more modern motorcycles. • Original braking system is primitive and offers limited stopping power, requiring anticipation and caution. • Parts availability for restoration and maintenance can be challenging and expensive due to its age and rarity. • Electrical system, if original, is likely to be unreliable and require frequent attention, impacting usability.Rule of thumb: under 125cc / 15HP → A1, under 47HP → A2, above → A.
