Built around Kawasaki's cross - motocross motorcycle platform, the 2011 Kawasaki KX 250F relies on a 249 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke powerplant. Internal engine geometry specifies a bore and stroke of 77.0 x 53.6 mm (3.0 x 2.1 inches) with a 13.5:1 compression ratio.
On the scales, the KX 250F measures 105.6 kg (233 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 945 mm (37.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,476 mm (58.1 in) wheelbase engineered for balanced agility and highway composure. The 7.19-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
