Positioned in Honda's sport motorcycle lineup, the 2020 Honda CBR300R pairs a 286 cc (17.5 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 34.9 HP (25.5 kW) at 10,500 rpm while maximum torque reaches 22.9 Nm (16.9 lb-ft), transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 122 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 CBR300R measures 161.9 kg (357 lbs) wet (curb), translating to a power-to-weight ratio of 0.22 HP/kg (4.64 kg per horsepower). Rider ergonomics and chassis geometry center around a 780 mm (30.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,379 mm (54.3 in) wheelbase engineered for quick, flickable steering geometry. The 12.87-liter (3.4 US gal) fuel tank paired with a rated consumption of 3.31 L/100 km provides an estimated theoretical range of roughly 389 km (242 miles) between fill-ups.
