1950 Sertum 250cc Sport
Frame no. 30679
Engine no. 70457
Founded in the 1920s in Milan, engineer Fausto Alberti's Sertum factory produced its first motorcycle - a 175cc single-cylinder four-stroke - in 1924. Many types of machine were made during the 1930s, ranging from a humble 120cc two-stroke single to a sturdy 500cc unitary construction sidevalve twin. Sertums competed in many endurance trials, proving quite successful in this role, and contracts were secured for the supply of machines to the Italian Army. Despite a reputation for first class quality, Sertum stopped production in 1952, its new models having failed to catch the public imagination. The 250cc single-cylinder sidevalve model offered here is a typical strongly built and well designed. Unitary construction of engine/gearbox, friction-damped rear suspension, blade-type girder forks, full-width hubs and separate magneto/dynamo are a few notable features. Presented in original condition and good working order, the machine is offered with ASI papers.

    Fondée dans les années 1920 à Milan, la société Sertum de l'ingénieur Fausto Alberti produisit sa première motocyclette – une 175 cm3 moncylindre quatre temps – en 1924. De nombreux types de motos furnet construits au cours des années 1930, allant de l'humble 120 cm3 deux temps à la robuste 500 cm3 monocoque bicylindre à soupapes latérales. Sertum s'engageait dans de nombreuses courses d'endurance, rencontrant un beau succès dans la discipline, débouchant sur des contrats avec l'armée italienne. Malgré une réputation pour sa qualité de premier ordre, Sertum cessa toute production en 1952, ses nouveaux modèles n'ayant pas rencontré l'adhésion du public. La monocylindre 250 cm3 à soupapes latérales offerte ici à la vente est un modèle typique, solidement construit et bien conçu. La construction unitaire du carter englobant moteur et transmission, la suspension arrière à friction, la fourche à lames de ressort, les moyeux larges et l'allumage à magnéto et dynamo séparées sont quelques-unes de ses caractéristiques les plus remarquables. Présentée dans son état d'origine, et en excellent état de marche, la machine est livrée avec un carnet chronologique.
