Technical Overview
2004 Ducati Monster 620 i.e. Dark Technical Analysis & Specification Breakdown
Engineered by Ducati for the naked motorcycle segment, the 2004 Ducati Monster 620 i.e. Dark pairs a 618 cc (37.7 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 60 HP (43.8 kW) at 8,250 rpm while maximum torque reaches 53.3 Nm (39.3 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 97.1 HP per liter and a 1,750 rpm working window between peak torque (6,500 rpm) and peak power (8,250 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 620 i.e. Dark measures 177 kg (390 lbs) wet (curb), translating to a power-to-weight ratio of 0.34 HP/kg (2.95 kg per horsepower). Rider ergonomics and chassis geometry center around a 770 mm (30.3 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.
