The Ducati Supersport and SS were a series of air-cooled desmodromic L-twin powered motorcycles manufactured by Ducati from 1988. The name came from the 1973 Ducati 750 Super Sport and the 1975 Ducati 750 and 900 Super Sport.
In 1975, the Italian motorcycle manufacturer launched the Ducati 900SS alongside the sleeved-down Ducati 750. The maker made 250 units each, but both machines were virtually identical.
The 1975 Ducati 900SS continued to use the right-side gear shifter, unlike the 1974 US regulations that said the gear shifter should be on the left side of the engine. However, several machines with a right-side shifter entered the American market.
In the visual department, the Ducati 900SS packed standard features, such as a half fairing with a large windscreen, a large, round headlight, a single seat, a dual chromed exhaust system with a muffler on each side, and lightweight wire-spoke wheels.
On the front end, a 38 mm Marzocchi telescopic fork softened the wheel and stopped by two 280 mm discs with a single-piston caliper. Two Marzocchi three-way adjustable side-mounted shock absorbers handled the rear wheel, and a single 260 mm disc achieved the stopping power.
In the performance department, the 1975 Ducati 900SS had its soul brought to life by an 864cc four-stroke air-cooled V-twin engine with two DellOrto carburetors in charge, delivering 80 hp with a peak force at 7,500 rpm.
