Engineered by Kawasaki for the super motard motorcycle segment, the 2010 Kawasaki KLX 125D relies on a 124 cc (7.6 cu in) air-cooled single cylinder, four-stroke powerplant. In factory specification, maximum torque reaches 10 Nm (7.4 lb-ft) at 6,400 rpm, 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 125D measures 114 kg (251 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 805 mm (31.7 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1,255 mm (49.4 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.
