DEMM was an Italian metalworking industry and motorbike manufacturer active from 1919 to 1988.
Founded at the behest of Giuliano Mazzini, the Museum of Motorcycles and Mopeds is the latest part of a cultural project aimed at revitalising tourism in the Porretta Terme area.
Inaugurated in March 2005, the Museum owes its birth to Giuliano Mazzini who dedicated his entire life to DEMM: he started as a mechanical designer, became first Production Director, then Managing Director and finally Vice President. Starting in 1985, together with his son Mosè, he began a long and painstaking task of research, recovery, restoration and valorisation of documents, prototypes and models related to the legendary production of motorbikes and mopeds.
The DEMM Museum of Motorcycles and Mopeds can be visited every day, including Saturdays and Sundays, subject to booking by e-mail or telephone call.

During the visit to the museum, it will be possible to see the Dick-Dick, the first DEMM moped built in 1956, the first two-stroke 125cc motorbike produced by the company, and the ‘Mini DEMM’, with a novel technical solution of the engine installed on the rear wheel hub.
One of the rooms is dedicated to the modern history of DEMM, where, in addition to the drafting machine used by Giuliano Mazzini to realise his designs, the fruits of his labour are neatly arranged, such as the horizontal cylinder engine, which equipped the Smily, Ping-Pong, Brio and Quick 2 production.
There is also a complete collection of precision and measuring instruments, made in the first half of the 1940s, and some valuable collector’s items, including a unique example of a ‘Pia Engine’ made by Engineer Enrico Bernardi in 1884: the world’s first example of an internal combustion engine.
The Demm Museum is located at Via Mazzini, 230, 40046 Porretta Terme, Bologna.
