2004 Ducati Monster S4 R Technical Analysis & Specification Breakdown
Positioned in Ducati's naked motorcycle lineup, the 2004 Ducati Monster S4 R features a 996 cc (60.8 cu in) liquid-cooled v2, four-stroke configuration. In factory specification, peak output is rated at 113 HP (82.5 kW) at 8,750 rpm while maximum torque reaches 95.5 Nm (70.4 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 113.5 HP per liter and a 1,750 rpm working window between peak torque (7,000 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 Monster S4 R measures 193 kg (425 lbs) wet (curb), translating to a power-to-weight ratio of 0.59 HP/kg (1.71 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.

Notes
The S4R is the top of the range Monster - the most powerful, highest-performance Monster ever. It all starts with the 996 cc Superbike engine and lightweight Superbike-derived trellis frame to ensure the perfect combination of power and handling. A Showa fully-adjustable front fork with low friction TiN treatment and a fully-adjustable Showa rear shock handle suspension duties.
