Displacement About Zundapp
Zündapp was a famous German motorcycle brand. The company was originally 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. 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. The company folded in 1984.
The first Zündapp motorcycle was the Z22 in 1921, the "Motorrad für Jedermann" (motorcycle for everybody), a simple and reliable design that was produced in large series. Zündapp's history of heavy motorcycles began in 1933 with the K-series. They introduced the closed engine case, a novelty at the time. (The "K" stands for "Kardanantrieb", i.e. enclosed driveshaft with two universal joints, a type of drivetrain, which these models featured.) The series encompassed models from 200 to 800 cc displacement and was a major success, increasing Zündapp's market share in Germany from 5% in 1931 to 18% in 1937. From 1940 on, Zündapp produced more than 18'000 units of the KS750, a sidecar with a driven side wheel and a locking differential for the German Wehrmacht.
Starting in 1931 Ferdinand Porsche and Zündapp develop the "Auto für Jedermann" (car for everybody), firt time the name "Volkswagen" was used. Porsche prefers the 4 Zylinder Flat4-Engine, but Zündapp used a watercooled 5 zylinder radial engine. In 1932 three Prototypes are running. All 3 Cars are lost during the war, the last was lost in 1945 in Stuttgart during a bombing raid.
After World War II, the company gradually shifted to producing smaller machines, for instance the "Bella" motorscooter, still a relatively heavy machine for its type. The last of the heavy motorcycles, and incidentally also one of its most famous models, was released in 1951: the KS601 (the "green elephant") with a 598 cc two cylinder engine.
