The debut of the 750SS and its desmodromic valvetrain in 1974 helped Ducati reached a new plateau of performance. Easily able to reach velocities in excess of 120 mph in a single bound, the 750SS reintroduced the world to Italian superbikes.

In 1976, a more powerful version of the SS appeared. Based on the non-desmodromic 860GT introduced in late 1973, the new 900SS added

desmodromics to the larger engine, pushing the performance envelope even further.

With a top speed of over 140 mph, the 900SS was as fast as anything the Japanese had to offer. The carefully sculpted steel fuel tank was surrounded by a bullet-shaped half fairing, and the solo saddle was backed by an aerodynamic tailpiece.

Together, these elements created a true racing image for the 900SS, which was only strengthened when Mike Hailwood rode a race-prepped version to victory at the Isle of Man TT.
