Built around Ducati's naked motorcycle platform, the 2005 Ducati Monster S4R features a 996 cc (60.8 cu in) liquid-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 115.5 HP (84.3 kW) at 9,500 rpm while maximum torque reaches 101 Nm (74.5 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 116 HP per liter and a 2,500 rpm working window between peak torque (7,000 rpm) and peak power (9,500 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 Monster S4R measures 181 kg (399 lbs) dry, translating to a power-to-weight ratio of 0.64 HP/kg (1.57 kg per horsepower). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,440 mm (56.7 in) wheelbase engineered for balanced agility and highway composure. The 15-liter (4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
