Licensed from Fiat, Puch developed it's own engine for the 500. This is one of the very last Puch 500's, with much less Puch's own parts than the older models (i.e. the fiat-gearbox without the Puch "Dynastarter") Restoration started by my brother in 1999, but sold unfinished in 2002. |

Puch's two-stroke double-piston engines
After Worldwar I, the Austrian industry was almost dead and people were jobless and hungry, no one thought of producing new motorbikes, so the bankers wanted to liquidate the little rest of the Puch factories, and sent the Italian engineer Giovanni Marcellino to Graz, to check this out.
After some weeks, Marcellino settled down in Austria, and invented this one-cylinder double-piston two-stroke-engine with one faster and one slower moving piston, resulting in an asymmetric control diagram. (the older Garelli double-piston-engine had two synchronous running pistons with conventional symmetric control-diagram, Marcellino's Puch engine was more inspired by big industrial counter-piston engines)
This picture shows the older double-piston engine with a fixed fork-rod and a longitudinal bearing in the right piston, build from 1923 ("Puch LM") to 1949 ("Puch 125").
The later models, from 1949 ("Puch 125TS") up to 1970 ("Puch 250SG"), had one fixed rod with a turnable pivot-rod on it.
