Longevity isn’t usually a characteristic of factory racing
motorcycles. Competition with the opposition is the target of any manufacturer
going racing, and that often means trying and discarding different designs

Although roughly a dozen were built for the factory race
team, Moto Guzzi Bicilindricas are few and far between nowadays, and until
