Positioned in Kawasaki's cross - motocross motorcycle lineup, the 2010 Kawasaki KX 250F relies on a 249 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 27 HP (19.7 kW) while maximum torque reaches 26 Nm (19.2 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 108.4 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 KX 250F measures 105 kg (231 lbs) wet (curb), translating to a power-to-weight ratio of 0.26 HP/kg (3.89 kg per horsepower). Rider ergonomics and chassis geometry center around a 955 mm (37.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,471 mm (57.9 in) wheelbase engineered for balanced agility and highway composure. The 7.94-liter (2.1 US gal) fuel tank supports practical everyday commuting and weekend road stints.
