2004 Ducati 999 S Technical Analysis & Specification Breakdown

Positioned in Ducati's sport motorcycle lineup, the 2004 Ducati 999 S pairs a 998 cc (60.9 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 136 HP (99.3 kW) at 9,750 rpm while maximum torque reaches 106 Nm (78.2 lb-ft) at 8,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 136.3 HP per liter and a 1,750 rpm working window between peak torque (8,000 rpm) and peak power (9,750 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 999 S measures 199 kg (439 lbs) wet (curb), translating to a power-to-weight ratio of 0.68 HP/kg (1.46 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 15.5-liter (4.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
