Built around Kawasaki's minibike, sport motorcycle platform, the 2005 Kawasaki KDX 50 relies on a 49 cc (3 cu in) single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 1.0 x 37.9 mm (0.0 x 1.5 inches) with a 5.9:1 compression ratio.
On the scales, the KDX 50 measures 38.1 kg (84 lbs) dry. Rider ergonomics and chassis geometry center around a 480 mm (18.9 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 861 mm (33.9 in) wheelbase engineered for quick, flickable steering geometry. The 2-liter (0.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
