THIS 1937 ES250/1 MODEL was typical of the quality machines produced by Bianchi. The firm was one of Italy’s longest-lasting motorcycle companies, manufacturing machines from the turn of the 20th century right up until 1967. It branched out into producing airplane engines, cars, and trucks, and still exists as a bicycle manufacturer.
This machine featured a shaft-driven overhead camshaft with exposed hairpin-valve springs. The cast-iron cylinder head had two exhaust ports with the pipes running down each side of the bike. The bottom of the engine featured an integral oil reservoir.
