Engineered by Honda for the naked motorcycle segment, the 2019 Honda CB300F relies on a 286 cc (17.5 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 29.5 HP (21.5 kW) at 8,500 rpm while maximum torque reaches 27 Nm (19.9 lb-ft) at 7,250 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 103.1 HP per liter and a 1,250 rpm working window between peak torque (7,250 rpm) and peak power (8,500 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 CB300F measures 157.9 kg (348 lbs) wet (curb), translating to a power-to-weight ratio of 0.19 HP/kg (5.35 kg per horsepower). Rider ergonomics and chassis geometry center around a 755 mm (29.7 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 1,560 mm (61.4 in) wheelbase engineered for planted straight-line stability. The 12.87-liter (3.4 US gal) fuel tank paired with a rated consumption of 3.02 L/100 km provides an estimated theoretical range of roughly 426 km (265 miles) between fill-ups.
