Friedhelm Zabel had been involved in motorcycle racing for some time before he began building his own engines. Early versions were Maico-based 620cc units, and in 1988 he built a water-cooled 685cc two-stroke for motocross sidecars producing over 80hp. Despite its extraordinary output, it weighed a mere 30kg. It was an immediate success.

1920 to 1925
Founded by Albert Roder and Karl Zirkel in Fürth, the marque is an acronym of Zirkel and Roder. The works were moved to Forchheim when Roder formed a new partnership with Rachinger in 1921.
The firm built 150, 250 and 350cc two-stroke machines using rotary valves from 1920 to 1925. The motorcycles were fitted with 3-speed gearboxes driving the rear wheel by belt or chain, and did very well in competition.
Roder and Zirkel left the company in 1923 and founded E.M.A.G. (later Ermag) in Erlangen. Roder went on to become a noted German designer, working with Victoria, Zundapp and NSU, where he was responsible for the Ultramax and the Quickly.
