This second volume on the history of the Bolognese motorcycle industry has been written and illustrated once more with the collaboration of the Museo del Patrimonio del Comune di Bologna (the Patrimony Museum of the Bologna City Council) to coincide with an exhibition on the subject. The book documents the difficult moments the companies and small local constructors faced, among them the financial straits of the market and the constraints imposed by the autonomy of those years, with doggedness, vitality and surprising inventiveness. As well as the production of motorcycles, this is the period in which the more economical means of three-wheel transport imposed themselves on the market. The motorbikes, three-wheeled vehicles and engines in the Bologna exhibition, which come from private collections, are presented in this book with a detailed series of photographs, while motorcycle history enthusiasts will find invaluable information and rare illustrations relative to the 16 marques, including Augusta, F.I.A.B., C.M., DEMM-S.CM.E.R.A., F.B., G.D., M.M., Moto Morini and others. The text is bi-lingual, precise and interesting and is published together with a wealth of documentation plus 200 pictures of the period.
