Built around Kawasaki's enduro - offroad motorcycle platform, the 2010 Kawasaki KLX 125 features a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, maximum torque reaches 10 Nm (7.4 lb-ft), transferring power to the rear wheel through a 5-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 54.0 x 54.4 mm (2.1 x 2.1 inches) with a 9.5:1 compression ratio.
On the scales, the KLX 125 measures 113 kg (249 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 830 mm (32.7 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,074 mm (42.3 in) wheelbase engineered for quick, flickable steering geometry. The 7-liter (1.8 US gal) fuel tank supports practical everyday commuting and weekend road stints.
