DUCATI ST4S (2003-2004) Specs, Performance & Photos

In 1997, the Italian motorcycle manufacturer created the ST family, a series of sport-touring motorcycles manufactured until 2007, comprising the ST2, ST3, ST3S, ST4, and ST4S models, intended to compete with other sport-touring machines like the Honda VFR.

The first model in the series was the Ducati ST2 model in 1997, followed by the ST4 in 1999, and joined by the Ducati ST4S introduced in 2001 and available from 2002. Compared to the ST4 model, the ST4S featured an improved suspension system and a larger engine.

In 2003, the Italian motorcycle manufacturer launched the Ducati ST4S, a sport-touring machine in its second year of production that came in the same package as the previous model, delivering the same technical and performance specifications.

For appearance, the bike was fitted with a full fairing, a windscreen, a single-piece dual seat with a passenger grab handle, a dual exhaust system with a muffler on each side, and five-spoke lightweight alloy wheels.

At the bike's core was a 996cc four-stroke liquid-cooled V-twin engine fed by an electronically controlled fuel injection system, delivering an output power of 117 hp with maximum strength at 8,750 rpm and 98 Nm (72 lb-ft) torque at 7,000 rpm.

The rear wheel was driven by a final chain drive and a six-speed manual transmission attached to the engine, pushing the machine to a top speed of 249 kph (155 mph).
