Built around Kawasaki's cross - motocross motorcycle platform, the 2025 Kawasaki Kx250 pairs a 249 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 78.0 x 52.2 mm (3.1 x 2.1 inches) with a 14.0:1 compression ratio.
On the scales, the Kx250 measures 109.5 kg (241 lbs) wet (curb). 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 1,485 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 6.21-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
