Technical Overview
2005 Ducati Monster S2R Dark Technical Analysis & Specification Breakdown
Built around Ducati's naked motorcycle platform, the 2005 Ducati Monster S2R Dark relies on a 803 cc (49 cu in) twin, four-stroke powerplant. In factory specification, peak output is rated at 76 HP (55.5 kW) at 9,500 rpm while maximum torque reaches 74 Nm (54.6 lb-ft) at 6,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 94.6 HP per liter and a 3,000 rpm working window between peak torque (6,500 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 Monster S2R Dark measures 173 kg (381 lbs) dry, translating to a power-to-weight ratio of 0.44 HP/kg (2.28 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 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
