Ducati 750GT Prototype (1970)

In 1970, Ducati’s mastermind Fabio Taglioni breathed life into his most iconic creation: a bevel-gear twin cylinder engine with a 90-degree V configuration. Dubbed “Pompone” by enthusiasts, this revolutionary powerplant would become the heartbeat of the legendary GT 750.

The prototype was built to perfection, with a focus on balance and performance. Taglioni’s vision was clear: a sports machine that would prioritize the engine as both its driving force and visual centerpiece. The result was a bike where form and function merged seamlessly.

With its single overhead camshaft driven by bevel-gear, this 750cc twin cylinder engine proved to be an engineering marvel. Its compact design and 76x75mm bore and stroke configuration made it the ultimate sports machine, ready to take on the world with its potent blend of power and agility. The Ducati 750GT Prototype was a game-changer, setting the stage for a motorcycle dynasty that would shake the very foundations of the industry.
