Positioned in Kawasaki's sport motorcycle lineup, the 2009 Kawasaki Ninja 250R pairs a 249 cc (15.2 cu in) liquid-cooled twin, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 40.1 HP (29.3 kW) while maximum torque reaches 22 Nm (16.2 lb-ft) at 6,200 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. With a specific output of 161 HP per liter, the engine character is placing it firmly in high-revving supersport territory where top-end breathing dominates.
On the scales, the Ninja 250R measures 170 kg (375 lbs) wet (curb), translating to a power-to-weight ratio of 0.24 HP/kg (4.24 kg per horsepower). Rider ergonomics and chassis geometry center around a 775 mm (30.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,400 mm (55.1 in) wheelbase engineered for quick, flickable steering geometry. The 18.16-liter (4.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
