1973 Advert for a German made Zündapp motor bike.
"The first Zündapp motorcycle was the model Z22 in 1921. This was the Motorrad für Jedermann ("motorcycle for everyone"), a simple, reliable design that was produced in large series. Zündapp's history of heavy motorcycles began in 1933 with the K-series. The "K" refers to the type of drivetrain that these models used, 'Kardanantrieb' meaning enclosed driveshaft with two universal joints."
