Maserati motorcycles were made by Maserati Candele and Accumulatori (Maserati spark plugs and batteries) of Modena. Although owned by the same parent company that also ran the automobile plant, the motorcycle division was completely separate. The company became instant manufacturers by buying an existing factor, Italmoto, and moving it from Bologna to Modena.
Lightweight, inexpensive to purchase and operate utility vehicle, the modern equivalent of this type of vehicle would be a Kawasaki Mule (which isn't lightweight or inexpensive). These motorcycles would be used for local deliveries in the narrow streets and alleys of Italy.
