A Brief Outline of the Italian Marque
Daldi e Luigi Matteucci established a small company in 1919 in Milan named Società Anonima Daldi which built automotive parts.
In 1928 the company name changed to Officine Meccaniche Daldi and Matteucci and finally, in 1939, to DEMM, an acronym for Daldi and Matteucci Milan.
The registered office remained in Milan, and a factory in Porretta Terme was erected which produced precision instruments and then, in 1952, began building of mopeds and light motorcycles.
In 1956 Demm established 24 world speed records in the 50cc class; this was followed by more competition success in the sixties, winning the Italian 50cc championship with their DOHC machine.
The Milan company was best known for its mopeds and 50cc sports bikes of the sixties and seventies built at the Porretta Terme factory. These were built using two and four-stroke engines mounted in both tubular and pressed metal frames.
Demm two-stroke engines of 50, 53 and 75 cc, and four-stroke 125cc and 175cc bevel-driven OHC engines were sold to many motorcycle manufacturers. Engine production ended in 1983, but they continued selling motorcycle related products until 1988 when focus shifted entirely to gears for vehicles and machinery, and the firm was eventually absorbed by ZF.
NB: DEMM or Demm? The term DEMM is used to refer to the company itself, whereas Demm is most commonly used in Italy and elsewhere in Europe to refer to the marque, e.g., Demm Super Sport 1971.
