Impressions of the reconstruction and restoration by Gustav Franke, 2018/19.

Zündapp never raced motorcycles developed specifically for competition. Instead, it took regular series-production machines and modified them specifically for their task. A "normal" KS 601 motorcycle and sidecar pairing was therefore used for the restoration. Many of the historical modifications – an elevated exhaust pipe, for example, enabled the machine to drive through water; armoring on the underside of the frame kept the oil pan from being punctured; a larger gas tank made it possible to run for longer distances; and a smaller, lightweight sidecar facilitated the requisite mobility on rough terrain – are now hard to find or entirely unavailable. That meant that some of these elements had to be reconstructed, and others were hunted down both in Germany and elsewhere.
