ST3

2005 Ducati ST3 Technical Analysis & Specification Breakdown

Engineered by Ducati for the sport touring motorcycle segment, the 2005 Ducati ST3 relies on a 992 cc (60.5 cu in) liquid-cooled v2, four-stroke powerplant. In factory specification, peak output is rated at 102 HP (74.5 kW) at 8,750 rpm while maximum torque reaches 100 Nm (73.8 lb-ft) at 7,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 102.8 HP per liter and a 1,500 rpm working window between peak torque (7,250 rpm) and peak power (8,750 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.

On the scales, the ST3 measures 235 kg (518 lbs) wet (curb), translating to a power-to-weight ratio of 0.43 HP/kg (2.3 kg per horsepower). Rider ergonomics and chassis geometry center around a 820 mm (32.3 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,430 mm (56.3 in) wheelbase engineered for balanced agility and highway composure. The 21-liter (5.5 US gal) fuel tank paired with a rated consumption of 4.5 L/100 km provides an estimated theoretical range of roughly 467 km (290 miles) between fill-ups, while factory top speed is listed at 237 km/h (147 mph).
