Ducati 900 SS (1975)

Ducati900 SS (1975)

The Ducati 900 SS: a road-legal production racer that embodied the raw, uncompromising spirit of its Imola 200 victory in 1972. This stunning V-twin superbike was born from the factory’s celebration of Paul Smart and Bruno Spaggiari’s historic win.

Its 864cc Desmo valve engine, featuring an impressive 79bhp at 7000rpm, delivered a rush of power that matched its razor-sharp handling. With clip-on handlebars, rear seat footrests, and twin Brembo front discs, the 900SS was a masterclass in minimalist design.

On the road, it was a visceral experience: a top speed of 135mph and a cruising speed of 100mph made it a thrilling companion for any rider. And when you wanted to really push its limits, the Ducati 900 SS revealed itself as a true track monster. With its raw, untamed character, this bike left an indelible mark on motorcycle history, cementing its place as one of the most iconic superbikes ever built.
