1903 Puch is a famous trademark, which was founded by the Austrian Johann Puch in 1899. With headquarters in Gràz, it emerged from the mechanical engineering field, to specialize in the manufacture of bicycles.
The first motorcycle had already been developed by 1903. This was a single cylinder, four stroke 244cc engine after which the manufacturing plant grew at such a rapid rate that it became, even before the Second World War, the main supplier of motorcycles in Austria.
1923 In 1923 the first two stroke engine was devised, with a subdivided cylinder sharing a single combustion chamber.
It is a new and innovative design, developed by the Italian engineer Giovanni Marcellina. He aligned two pistons inside a single subdivided cylinder, using normal gearing, supported by a single Y-shaped connecting rod, which impose a rotatory motion on the drive shaft , also still normal with respect to gearing; dual conical coupling mounted on the inside of the driveshaft conveys the power directly to the transmission gear. The two pistons are fed by two carburetors, which, depending on the model, are positioned both behind and on either side of the cylinder.
This unusual configuration started a tradition which endured throughout the lifespan of Puch: double piston, double carburetor, double exhaust...
The first example realized according to this unusual principle was a 122cc motorcycle, which was joined, in later years by other versions in a 175cc, 250cc and 350cc even an astounding 500 dual cylinder, also with the familiar cylinder sharing a common combustion chamber design, followed in 1954.
1934 In 1934 following the joining and incorporation of Steyer Werke AG and the Osterreichische Daimler Motoren, Puch became the largest Austrian industrial group and retained this status to the end of its glorious existence.
1950 Puch motorcycles showed up regularly at most races such as the Alpenfahrt and the Six Days after the war and it is therefore not surprising that even since the early days Puch could be found with all its main models qualifying at all the important European competitions.
