Built around Kawasaki's enduro - offroad motorcycle platform, the 2017 Kawasaki KLX 140G features a 144 cc (8.8 cu in) air-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 58.0 x 54.4 mm (2.3 x 2.1 inches) with a 9.5:1 compression ratio.
On the scales, the KLX 140G measures 99 kg (218 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 861 mm (33.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,331 mm (52.4 in) wheelbase engineered for quick, flickable steering geometry. The 5.68-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
