Ducati 851 SP2 (1990)

Ducati 851 SP2 (1990)

The Ducati 851 SP2: a machine born from the pursuit of perfection in the Italian Sport Production series. Its 888cc engine, bred for dominance on the track, sings with a throaty growl, its desmodromic valves opening and closing with precision as it unleashes a torrent of power.

With two injectors per cylinder and closer-ratio gearing, the SP2’s engine character is one of relentless thrust and agility. Its handling is just as impressive, thanks to the upside-down Hlins fork, high-quality shock absorber, and fully floating Brembo front disc brakes.

Riding the Ducati 851 SP2 is an experience unlike any other, a symphony of speed and agility that defies description. Where others may falter, this Italian thoroughbred delivers unparalleled performance in 1990, its aluminum rear subframe and Termignoni exhaust system rounding out its impressive package.
