At the heart of the 2021 Honda CB-F Concept prototype - concept model motorcycle, Honda pairs a 998 cc (60.9 cu in) liquid-cooled in-line four, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 143.5 HP (104.7 kW) at 10,500 rpm while maximum torque reaches 104 Nm (76.7 lb-ft) at 8,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 143.8 HP per liter and a 2,250 rpm working window between peak torque (8,250 rpm) and peak power (10,500 rpm), the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
