At the heart of the 2007 Kawasaki KX125 cross - motocross motorcycle, Kawasaki utilizes a 124 cc (7.6 cu in) single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 54.0 x 54.5 mm (2.1 x 2.1 inches) with a 10.9:1 compression ratio.
On the scales, the KX125 measures 87 kg (192 lbs) dry. Rider ergonomics and chassis geometry center around a 945 mm (37.2 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,470 mm (57.9 in) wheelbase engineered for balanced agility and highway composure. The 8.2-liter (2.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
