The exhibition focuses on the golden age of Bologna as far as the motorcycle production is concerned. Actually, from the 1920s to 1950s, the Bologna region was an important Italian centre in this field, because of the large number of small and medium companies manufacturing finished motorcycles (over 70 in that period, though with changing fortune), and an even larger number of firms capable of supplying all the parts necessary to assembly any kind of motorcycle. The adventurous story of the C.M company - founded by Mario Cavedagni, goes back to those years, and it is similar to the story of many other Bologna companies.
The exhibition Moto bolognesi C.M - Trent'anni memorabili 1929-1959(C.M Bologna motorcycles - Thirty unforgettable years) features 15 motorcycles dating back to the 1930s-1950s, among the most important models produced by C.M, and the most interesting pieces belonging to the collections of Piedmont, Lombardy, Veneto, and Emilia-Romagna regions. Three screenings also feature a rich collection of photos and catalogues, most of them never seen before.
