Puch is a manufacturing company located in Graz, Austria. The company was founded in 1899 by the industrialist Johann Puch and produced automobiles, bicycles, mopeds, and motorcycles.
In 1923 the Italian engineer and FIAT agent Giovanni Marcellino is said to have been sent by the banks to wind up the Puch factory in Graz. Instead of which, within a few weeks he had settled down to live in the town, designing and then producing a new version of the split-single.

Taking his inspiration from industrial counter-piston engines, the new engine benefited from the improved breathing of the Italian original, to which he added asymmetric port timing. In 1931 Puch won the German Grand Prix with a supercharged split-single, though in subsequent years the split-singles of DKW did better. In 1928 the company merged with Austro-Daimler into the new Austro-Daimler-Puchwerke. This company in its turn merged in 1934 with Steyr-Werke AG to form the Steyr-Daimler-Puch conglomerate.Displacement: 223 cc.Cylinder: 2 – split single.Engine type: 2-stroke.Bore / Stroke: 45 x 70 mm.Power: 4.5hp @ 3.500 rpm.Compression Ratio: 1 : 4.8.Weight: 83 kg.Top Speed: 75 km/h.
