Aermacchi 433 cm3 Ala D'Oro Replica 1970
Frame no. 250882
Engine no. 190688
Cette Ala d'Oro replica a été construite à partir d'un cadre de routière restauré acheté auprès d'un ancien pilote de Santo Stefano Ticino près de Milan (la plaque d'identification est toujours en place). Les fourche, étriers et freins sont des Ceriani originaux et les amortisseurs des Girling originaux. Toute la boulonnerie est correcte et le compte-tours est un Veglia d'époque conforme à l'origine. Le moteur intègre des carters Aermacchi 350 amélioré par le montage d'un roulement à billes supplémentaires comme sur l'Ala d'Oro, modifié pour recevoir un cylindre de 82 mm d'alésage. Allégé et équilibré, le vilebrequin 350 Ala d'Oro donne une cours ede 82 mm pour une cylindrée d'environ 433 cm3. L'arbre à cames, les bielles forgées, le couvercle moteur en magnésium et l'embrayage à sec sont tous d'origine Ala d'Oro.

Les autres spécifications notables sont un double allumage, un carburateur Dell'Orto SS42 et une boîte de vitesses renforcée. Les pignons intermédiaires renforcés de cette dernière proviennent d'une AMF Harley-Davidson 350SS afin de répondre au gain de puissance obtenu. Les pignons de première et de cinquième sont d'origine. Achevée en 2011, cette superbe Ala d'Oro replica n'a effectué que deux parcours d'essai sans jamais connaître la piste.

  • 1970 Aermacchi 433cc Ala D'Oro Replica
    Frame no. 250882
    Engine no. 190688
    .



    This Ala d'Oro replica has been constructed around a restored roadster frame acquired from an ex-racer from Santo Stefano Ticino near Milan (the VIN plate is still in place). The fork, yokes and brakes are original Ceriani, and the shock absorbers are original Girling. All nuts and bolts are correct and the rev counter is an original period Veglia. The engine incorporates 350 Aermacchi crankcases, upgraded with an additional ball bearing as in the original Ala d'Oro, which have been modified to accept an 82mm bore cylinder. Lightened and balanced, the 350 Ala D'Oro crankshaft has a stroke of 82mm, giving the engine a capacity of approximately 433cc. The camshaft, forged connecting rod, magnesium engine side cover and dry clutch are all Ala d'Oro components.

    Other noteworthy features include twin-plug ignition, a Dell'Orto SS42 carburettor and an up-rated gearbox. The latter's intermediate gears are stronger components from an AMF Harley-Davidson 350SS, necessitated by the enlarged engine's increased power. First and fifth gears are original. Completed in the 2011, this beautiful Ala D'Oro replica has had only two 'shakedown' outings and has never been ridden on a racetrack.
