The bore / stroke of the two-stroke engine was equal to the EM 300 and also produced 9 hp at 3200 rpm. Top speed was about 90 km / h. The frame then consisted of metal tubes, far from the well-known later aluminum injection molding process. A Z 300 ran in 1929, the last year of this type, as 30,000 Zündapp from the production line.
