Ducati 750 GT 1970 L-twin prototype motorcycle photo press photograph

Description

A superb and rare photo of the famous prototype of the
Ducati 750 GT
. This photo dates from August 1970, and it shows the last prototype before production.
It was the first Ducati with the thesedays so very famous V-twin engine. The bevel-gear twin cylinders with a 90° V configuration, long known as an “L-twin” configuration, was put on paper by Fabio Taglioni on
March 20, 1970
. It was not long before the prototype was on the bench. Taglioni’s envisioned the bike as an essential sports machine. The distribution used the same single overhead camshaft driven by bevel-gear as the single-cylinders, while the capacity of 750 cc was obtained with a bore and stroke of 76 x
75 mm
. The prototype was built rapidly. The result: a very personal sort of motorbike in which the engine played the central role, even stylistically. The final bike was very similar to the prototype. The 750 GT appeared in June 1971. Its frame was more proportionate than that of the prototype, while the carburetors were
30 mm
Amal Concentrics. It was also fitted with a Lockheed front disk brake. Its very name, Gran Turismo, immediately revealed that it was no sports bike, but the potential of this twin was immediately apparent to its enthusiasts.

This is a very nice non period photo that reflects a magic period of Ducati history, it definitely is a classic shot. It is rare to obtain a photo like this, therefore it is printed in a nice large format of approx. 7.7" x 11.5" (19.5 x 29.2 cm). It is great the way it is, and would look gorgeous when framed.
