Carlo Guzzi's first prototype motorcycle of 1919 was unconventional in so far as its single-cylinder engine was installed horizontally, a feature that by the end of the 1930s had established itself as a Guzzi hallmark. Guzzi's 4-valve prototype was exceptionally advanced for its day, though the Normale model that entered production in 1921 was necessarily less ambitious, the most obvious difference being its engine's inlet-over-exhaust valve arrangement, adopted to reduce costs. Continuing the Guzzi tradition of technological innovation, the firm introduced the first production motorcycle with a sprung frame – the GT – in 1928, backing its faith in the concept by sending Carlo's brother Giuseppe on a marathon trip through Europe to Scandinavia aboard one of the new 'springers'. Guzzi continued to offer cheaper rigid-framed models and kept faith with the 'IOE' engine into the 1930s. Two of the last such models were the 'S' and 'GTS', which were newly introduced for 1934, the former with rigid frame and hand gear change, the later with sprung frame and rocking-pedal foot change. Production of both ceased in 1940 and after WW2 all of Guzzi's large-capacity four-stroke roadsters would have overhead valves. This particular GTS has been restored to original specification.

    En 1919, le premier prototype de moto de Carlo Guzzi était inhabituel en ce qu'il était équipé d'un monocylindre horizontal, une caractéristique qui, à la fin des années 1930, était devenu la marque de fabrique des Guzzi. Le prototype à quatre soupape de Guzzi était exceptionnellement moderne pour l'époque, bien que le modèle Normale qui entra en production en 1921 ait été forcément moins ambitieux, la différence la plus notoire étant l'architecture à soupapes d'admission au-dessus des soupapes d'échappement de son moteur, adoptée pour réduire les coûts de production. Perpétuant la tradition d'innovation technique de Guzzi, la firme présenta la première moto de série à cadre suspendu – la GT – en 1928, affirmant sa confiance en ce nouveau concept en envoyant le frère de Carlo, Giuseppe, faire un marathon autour de l'Europe, jusqu'en Scandinavie, sur une des nouvelles « suspendues ». Guzzi continua d'offrir des modèles plus économiques à cadre rigide et garda toute sa confiance au moteur IOE jusqu'aux années 1930. Deux de ces derniers modèles étaient les S et GTS, fraîchement présentés en 1934, le premier avec cadre rigide et changement de vitesses au guidon, le second avec cadre suspendu et changement de vitesses au pied par levier basculant. La production des deux modèles prit fin en 1940 et après la deuxième guerre, toutes les Guzzi de grosse cylindrée à moteur quatre temps allaient être équipées de soupapes en tête. Cette GTS particulière a été restaurée aux spécifications d'origine.
