1957 Benelli 500cc 4-valve DOHC

1957 Benelli 500cc 4-valve DOHC

Bonham's sold this prototype in February of this year for 16,100 Euros:

Italy's oldest surviving motorcycle manufacturer, Benelli was founded in 1911 by the six Benelli brothers. Now Chinese-owned, although still based in its home town of Pesaro [Italy], Benelli is best known for its Grand Prix successes in the 1950s and 1960s, when it secured two 250cc World Championships, and also for its outrageous six-cylinder road bikes of the 1970s.

According to our vendor, the machine offered here is a 4-valve prototype. Other notable features include gear drive to the twin overhead camshafts and an Oldani TLS front brake, while the frame has clearly been influenced by Norton's 'Featherbed'. No Documents.

Gear driven, dual over head camshafts on a single cylinder engine. Crazy, man.
