Made in France
1951 to 1958
Centre D'Etudes Moteurs à Explosion et Combustion
The company was founded in 1945 as Centre de montage et de récupération (CMCR) (English: Assembly and Repair Centre) at Neuilly-sur-Seine.
The company was located in Bièvres and from 1951 to 1958 produced motorcycles very similar in design to BMW models of the same era.
Several pages of technical information here:
A rough translation of the French begins:
The engine of the CEMEC is a 4-stroke gasoline engine, 2 opposed cylinders (flat twin) with a total capacity of 748 cm 3 for the L7 and C8, 497 cm 3 for the C5.
The engine type L 7 is side valve and the types C 8 and C 5 are overhead valves.
The aluminium crankcase is in two halves, the division between the axis of the cylinders.
The barrels are cast iron with cooling fins, bore is 78 mm.
The valve guides were directly bored in the casting.
Ignition is by a double coil Ducellier 6 volts. The C.E.M.E.C. is equipped with a 60 watt dynamo France, driven by a chain. The ignition timing is controlled by a hand lever located on the handlebar.

In my book 'Enzyklopädie des Motorrads' it is told, that Cemec (Centre D'Etudes Moteurs à Explosion et Combustion) was located in Bièvres. The company produced bikes from 1951 - 1958. -- Leiterw at aol dot com
