2016 Kawasaki Ninja 400 Technical Analysis & Specification Breakdown

At the heart of the 2016 Kawasaki Ninja 400 sport motorcycle, Kawasaki features a 399 cc (24.4 cu in) liquid-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 44 HP (32.1 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 110.3 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 Ninja 400 measures 209 kg (461 lbs) wet (curb), translating to a power-to-weight ratio of 0.21 HP/kg (4.75 kg per horsepower). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,405 mm (55.3 in) wheelbase engineered for quick, flickable steering geometry. The 15-liter (4 US gal) fuel tank paired with a rated consumption of 4.17 L/100 km provides an estimated theoretical range of roughly 360 km (224 miles) between fill-ups.
