Zündapp KKS 500

The Zündapp KKS 500 was a heavy shaft-driven motorcycle that Zündapp produced from 1936 to 1938, and it was the first Zündapp with a foot gear change. Only 170 examples were built, which makes it a rarity among the marque road machines of the 1930s. It belonged to the K-series that began in 1933, in which the letter K refers to the Kardanantrieb, an enclosed driveshaft with two universal joints, and it sat in the 500 cc class between the K 500 and the larger K 800 flat four. A model list describes the KKS-500 as a 496 cc horizontally opposed twin with side valves.
