Engineered by Kawasaki for the super motard motorcycle segment, the 2020 Kawasaki KLX250S pairs a 249 cc (15.2 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, maximum torque reaches 20.6 Nm (15.2 lb-ft) at 7,000 rpm, transferring power to the rear wheel through chain final drive. Internal engine geometry specifies a bore and stroke of 72.0 x 61.2 mm (2.8 x 2.4 inches) with a 11.0:1 compression ratio.
On the scales, the KLX250S measures 135 kg (298 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 890 mm (35 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,430 mm (56.3 in) wheelbase engineered for balanced agility and highway composure. The 7.57-liter (2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
