Positioned in Kawasaki's sport motorcycle lineup, the 2020 Kawasaki Ninja 400 KRT SE features a 399 cc (24.4 cu in) liquid-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 44.8 HP (32.7 kW) at 10,000 rpm while maximum torque reaches 38 Nm (28 lb-ft) at 8,000 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 112.3 HP per liter and a 2,000 rpm working window between peak torque (8,000 rpm) and peak power (10,000 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 KRT SE measures 168 kg (370 lbs) dry, translating to a power-to-weight ratio of 0.27 HP/kg (3.75 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 1,370 mm (53.9 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints.
