Initially Zündapp considered modifying their KS 600 model in order to meet the OKH demands, but it was soon clear that the KS 600 was not suitable for further development: the frame, engine, transmission, front fork and many other parts would have to be either reinforced or receive substantial modifications to meet the new criteria.

[1] Some units were built with eight-speed dual-ratio transmission, including reverse gear customary on sidecars.

Equipment included a spare wheel, holders for ammunition cases and gasolene canister, plus a tow bar for a trailer.

Moreover, BMW and Zündapp also agreed, as demanded by the OKH, to standardize as many components as possible, in order to both streamline production, as well as logistics and (field) maintenance / repairs, through interchangeable spare parts, usable on both models.

The series production started in the spring of 1941, and in eight years Zündapp produced 18,695 KS 750 in their Nuernberg factory.
