Built around MV Agusta's prototype - concept model motorcycle platform, the 2023 MV Agusta Concept 921 S pairs a 921 cc (56.2 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 115.5 HP (84.3 kW) while maximum torque reaches 115.3 Nm (85 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 125.4 HP per liter, 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 Concept 921 S measures 205 kg (452 lbs) dry, translating to a power-to-weight ratio of 0.56 HP/kg (1.77 kg per horsepower). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,465 mm (57.7 in) wheelbase engineered for balanced agility and highway composure. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.

Torque is useful for judging real-world pull, especially for touring, commuting and loaded riding.
Seat Height
Check the seat height against your inseam and riding posture before choosing a motorcycle.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
Suspension
