A manufacturer of gears, machine tools and measuring instruments, Milan-based DEMM diversified into motorcycle production after WW2, and is best remembered for its fast and stylish mopeds and lightweights. In the 1950s the company held many world speed records in the ‘tiddler’ classes, and in 1961 one of its twin-cam racers won the Italian 50cc Championship with their DOHC machine.

The company began by making proprietary engines before launching its first complete machine – the Dik Dik moped – in 1956. DEMM’s mopeds were widely exported to other parts of Europe and to North America, and sold well despite quirky model names such as ‘Smily’ and ‘Ping-Pong’. Production of DEMM motorcycles ceased in the mid-1980s. The moped comes with Dutch registration papers.
