In a series of strokes, Ducati had divided its liquid-cooled, fuel-injected, four-valve competition department from its two-valve, air-cooled street bike fans. The 900 SS was so well sorted that it changed very little until it was replaced in 1997. The 900 Super Sport remains a definitive Ducati experience, and many have been kept for lengthy periods by proud owners.

The troublesome Weber carburettor was replaced with Mikuni flat slides in 1990, and after this tweak performance almost matched the fuel injected 907 IE Paso. The rake was steepened to 25 degrees, a shorter swing-arm reduced the wheelbase, and longer rear shock quickened the steering. Showa adjustable front forks replaced the Marzocchis, and bigger Brembo disc brakes were fitted. The clip-on bars were raised and the foot-pegs lowered.
