Built around Kawasaki's enduro - offroad motorcycle platform, the 2026 Kawasaki Klx140R relies on a 144 cc engine powerplant. Internal engine geometry specifies a bore and stroke of 58.0 x 54.4mm with a 9.5:1 compression ratio.
On the scales, the Klx140R measures 205 kg (452 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 30 mm (1.2 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 49 mm (2 in) wheelbase engineered for quick, flickable steering geometry. The 1.5-liter (0.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
