This is the motorcycle drive our fathers/grandfathers are accustomed to. The basis is formed by a two-stroke single cylinder engine, cooled by the air stream. The engine is directly screwed onto the (red) frame. The exhaust outlet port ends in front at the side in a chrome plated exhaust gas pipe. The (yellow) inlet port was connected in the rear to the carburettor. The carburettor air is sucked from the spot where now the (blue) arrow is visible. In front of it via a stopcock the fuel pipe, coming from the tank which is positioned higher up. The fuel pipe ends in the (cut open) float chamber.
Thanks to the opening of the lower engine case you can recognise the multi-disc wet clutch and the large gearwheel linked form-conclusively with it, going to the gearbox (primary shaft). The engine speed is reduced (for the first time). Also the kick-starter is recognizable which could also be connected with the gearwheel during the start process. Below there is a foot control.The picture on top displays a cut 2-stroker manufactured by MZ in 1956. Its principle design was used until 1993 in Zschopau and still today Kanuni (Turkey) makes use of it, but with a changed case, a different performance and a different gearbox. 06/08
