At the heart of the 2005 Kawasaki KX 250 cross - motocross motorcycle, Kawasaki utilizes a 249 cc (15.2 cu in) liquid-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 66.4 x 72.0 mm (2.6 x 2.8 inches) with a 10.5:1 compression ratio.
On the scales, the KX 250 measures 97 kg (214 lbs) dry. Rider ergonomics and chassis geometry center around a 965 mm (38 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,481 mm (58.3 in) wheelbase engineered for balanced agility and highway composure.
