Engineered by Kawasaki for the enduro - offroad motorcycle segment, the 2025 Kawasaki Klx140Rl features a 144 cc engine configuration. Internal engine geometry specifies a bore and stroke of 58.0 x 54.4 mm with a 9.5:1 compression ratio.
On the scales, the Klx140Rl measures 205 kg (452 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 800 mm (31.5 in) seat height — offering a neutral standover height that accommodates most average-inseam riders without sacrificing cornering clearance, combined with a 1 mm (0 in) wheelbase engineered for quick, flickable steering geometry. The 5.8-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
