CEMEC was a French motorcycle company that manufactured motorcycles from 1948 until 1958. The company was based at Bievres and was derived from CMR which, known before as CMRM ( Centre de Montage et de Réparation) was created to be in charge of the motorcycles that were left behind by the German Army in the Second World War.

CEMEC stands for Center for the Study of Explosion Motors. The main objective of the company was to ascertain that every useful reminder was of use to the French police. The company manufactured its lone model, the L7. It was a 750cc motorcycle that was duplicated at least 1500 times and was built from 1958 to 1954. After its completion, the company shut down but was acquired the following year by Ratier which was a company that built aircraft components. Ratier was based in Montrouge.

The only model of the company was the L7. This 750cc bike, cloned 1500 times, was manufactured from 1948 to 1954, when the company closed the doors. One year later, in 1955, CEMEC was purchased by Ratier, an aircraft components manufacturer from Montrouge. Ratier was known for its 1926 746cc car and motorcycles which were manufactured in 1959 and 1962. This was after taking over (Centre d'Études de Moteurs à Explosion et à Combustion) CEMEC’s business.

The engines of these machines were flat-twins and they featured the WWII MBW R12 design which is what inspired their creation. The L7 produced eight releases which were L7-1 through L7-8. Ratier continued with the series of motorcycles producing the 600cc series C6S under its own brand. Thus model could hit speeds of 160 km/h because of its 32 HP which met the approval of De Gaulle. He did not want to have anything to do with German motorcycles.

Ratier was later acquired by Thomson CSF which was an important electronics and defense contractor. The company attempted to produce a new model in 1962 but did not get anywhere with that plan. They, therefore, concentrated their efforts on manufacturing micro-electronics for their Mirage warplane. CEMEC was done for and no further attempts were made to reopen it.
