Moto Guzzi Falcone? Moto Guzzi - yes but not a Falcone - that had a horizontal engine. This is a smaller model with a vertical engine. Some research needed. Should be a 1971 Nuovo Falcone Militare( if that,was a model born initially for replace older Falcone 500s into Polizia Stradale and Carabinieri Corps vehicles' fleets) Othewise,a 1960 to 1975 Stornello Should be n'importe quoi, MAIS PAS UNE GUZZI, bon sang! Faut arrêter d'identifier quand on sait pas, bourdel! Cela dit, le garde-boue ressemble à une Gilera...
Probably a Gilera B300 from the '60's
