2021 Ducati Monster Plus Technical Analysis & Specification Breakdown

Positioned in Ducati's naked motorcycle lineup, the 2021 Ducati Monster Plus pairs a 937 cc (57.2 cu in) air-cooled v2, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 111 HP (81 kW) at 9,250 rpm while maximum torque reaches 93 Nm (68.6 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 118.5 HP per liter and a 2,750 rpm working window between peak torque (6,500 rpm) and peak power (9,250 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 Plus measures 188 kg (414 lbs) wet (curb), translating to a power-to-weight ratio of 0.59 HP/kg (1.69 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 1,474 mm (58 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.
