NSU 501 OSL and TS (1930-36)

The NSU 501 OSL and TS were motorcycles produced by the German company NSU between 1930 and 1936. These motorcycles had a reputation for being reliable and well-built, and were popular among riders in Europe and beyond.

The NSU 501 OSL was a single-cylinder bike that featured a 500cc engine and a four-speed gearbox. It had a top speed of around 75 miles per hour and was often used for touring and long-distance rides. The TS model, which was introduced in 1931, was a sportier version of the OSL that had a higher compression ratio and a top speed of around 85 miles per hour.

Both the OSL and TS models had a distinctive telescopic fork suspension system that was ahead of its time. This made the motorcycles more stable and easier to handle than many of their contemporaries.
