2015 Honda CBR400R Technical Analysis & Specification Breakdown

Positioned in Honda's sport motorcycle lineup, the 2015 Honda CBR400R relies on a 399 cc (24.4 cu in) liquid-cooled twin, four-stroke powerplant. In factory specification, peak output is rated at 46 HP (33.6 kW) at 9,500 rpm while maximum torque reaches 37 Nm (27.3 lb-ft) at 7,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 115.3 HP per liter and a 2,000 rpm working window between peak torque (7,500 rpm) and peak power (9,500 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 CBR400R measures 192 kg (423 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.17 kg per horsepower). Rider ergonomics and chassis geometry center around a 785 mm (30.9 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,410 mm (55.5 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank paired with a rated consumption of 2.52 L/100 km provides an estimated theoretical range of roughly 595 km (370 miles) between fill-ups.
