Sport Touring ST2/ST4

SPORT TOURING2

The Ducati ST2 is a spirited combination of performance and usability. With its powerful fuel injected 944cc L-Twin engine and rigid tubular steel trellis frame, the ST2 delivers the performance of a sport bike while its relaxed ergonomics and quality of design provide the
all-comfort of a touring bike. Smooth and refined, the ST2 is one of the most versatile motorcycles
in the world, striking the perfect balance between sport and touring.

SPORT TOURING4

The Ducati ST4 occupies a position at the performance end of the Sport Touring spectrum. The ST4 combines elements of a true sport bike, like Ducati's powerful fuel injected 916cc four valve
Superbike engine, with the same innovative design features found on the ST2. As versatile as it is
fun to ride, the ST4 lets you enjoy the excitement and performance of a Superbike in comfort.

Evolution:
Ducati's interpretation of the Grand Touring motorcycle while retaining a racing spirit in terms of engine power and the characteristics of the ride

ST bikes are descendants of the Ducati Paso which represented a well-thought out riding position that it became the favorite high speed, long-distance touring bike of many experienced riders

ST2 was launched in 1997 and proceeded to win the 1997 MCN magazine "Sport Tourer of the Year" Award

1998 marked the introduction of the ST4, a more powerful and technologically advanced 4-valve version of the ST2
