1924 Della Ferrera 130cc Lightweight
Frame no. 28-218
Engine no. 26-218
The Della Ferrera brothers founded their motorcycle company in Turin in 1909 and swiftly grew to become one of Italy's foremost manufacturers. Their first motorcycle was powered by a 330cc four-stroke single, which was progressively increased in size. A 500cc v-twin with overhead valves was added to the range in 1913, followed by a 500cc four-valve single the following year. Production continued after The Great War with a range of predominantly four-stroke models of varying capacities, including some very successful 500cc racers powered by overhead-camshaft engines, the cams being driven by exposed chains. In a departure from the norm, in 1924 Della Ferrera introduced a 130cc two-stroke lightweight, which was unusual in employing an engine of the 'split single' type most commonly associated with Garelli and Puch. In the Della Ferrera design the two pistons shared the single connecting rod, employing a long gudgeon pin; an elongated combustion chamber bridged the two cylinders, one of which incorporated the inlet and transfer ports while the other looked after the exhaust phase. This original and un-restored example of Della Ferrera's extremely rare two-stroke is offered with extracts from related literature.

    Les frères Della Ferrera fondèrent leur compagnie de motocyclettes à Turin en 1909 et devinrent rapidement l'un des plus importants constructeurs italiens. Leur première moto était propulsée par un monocylindre quatre temps de 330 cm3 qui fut régulièrement réalésé. Un bicylindre en V de 500 cm3 à soupapes en tête fut ajouté à la gamme en 1913, suivi d'un monocylindre de 500 cm3 à quatre soupapes, l'année suivante. La production reprit après la Grande Guerre avec une gamme composée essentiellement de quatre temps de différentes cylindrées, dont quelques racers 500 cm3 à arbre à cames en tête, entraîné par des chaînes apparentes, très performants. Sortant de ses habitudes, en 1924 Della Ferrera présenta une deux temps de 130 cm3 allégée, originale par son moteur de type double monocylindre, plus généralement associé aux productions de Garelli et Puch. Sur le modèle Della Ferrera, les deux pistons partageaient la même bielle, par le biais d'un long axe de piston. Une chambre de combustion allongée reliait les deux cylindres dont l'un portait les lumières d'admission et de transfert, tandis que l'autre était affecté à l'échappement. Cet original exemplaire de Della Ferrera non restauré à rare moteur deux temps est proposé avec des articles d'époque.
