Zündapp was a major German motorcycle manufacturer founded in 1917 in Nuremberg by Fritz Neumeyer, together with the Friedrich Krupp AG and the machine tool manufacturer Thiel under the name "Zünder- und Apparatebau G.m.b.H." as a producer of detonators (Zünder- und Apparatebau is German for Igniter and Apparatus). In 1919, as the demand for weapons parts declined after World War I, Neumeyer became the sole proprietor of the company, and two years later he diversified into the construction of motorcycles.
Following World War II, Zündapp expanded into the microcar, moped and scooter markets. The company collapsed in 1984.

In 1936, Zündapp launched the KS 500 ("Kardan Sport" 500), a sporty touring version of the K series. Instead of side-valve (SV) valves, the engine now featured overhead valves (OHV). With approximately 50 percent more power, the KS 500 was considerably more spirited than the K 500. Even more nimble was the KKS 500 variant, combining the lightweight box frame with the 500cc OHV boxer engine, but therefore no longer suitable for sidecar use. The foot-operated gearshift was also sporty, although it was still available in combination with a tank-operated gearshift and was located on the right, where the brake pedal was also located.


This Zündapp KS500 has been nicely restored a number of years ago, it is in a good running and rideable condtion. It is equipped with hard to find components characteristic for the KS500, like special gearbox with hand- and foot gear change control and front fork with oil-filled vibration damper.
Equipments include Norris electric lighting system and horn, toolbox and rare to find air-filter, connecting the two carburettors.

The model KS500 was a real sports motorcycle in the 'KS' production line from Zündapp, it had the advantage of lighter components and sportier look compared to the other models in the 'KS' line.
Today the KS500 is one of the most sought-after model of any pre-war Zündapps ever produced.
