Technical Overview
2005 Ducati ST4 S ABS Technical Analysis & Specification Breakdown
At the heart of the 2005 Ducati ST4 S ABS sport touring motorcycle, Ducati pairs a 996 cc (60.8 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 89.1 HP (65 kW) at 9,500 rpm while maximum torque reaches 105 Nm (77.4 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 89.5 HP per liter and a 2,250 rpm working window between peak torque (7,250 rpm) and peak power (9,500 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.
On the scales, the ST4 S ABS measures 206 kg (454 lbs) dry, translating to a power-to-weight ratio of 0.43 HP/kg (2.31 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 supports practical everyday commuting and weekend road stints.
