Built around Kawasaki's enduro - offroad motorcycle platform, the 2025 Kawasaki Klx140Rf relies on a 144 cc engine powerplant. 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 Klx140Rf measures 205 kg (452 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 860 mm (33.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, 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.
