Built around Kawasaki's cross - motocross motorcycle platform, the 2020 Kawasaki KX100 pairs a 99 cc (6 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 52.5 x 45.8 mm (2.1 x 1.8 inches) with a 10.2:1 compression ratio.
On the scales, the KX100 measures 77 kg (170 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 871 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,311 mm (51.6 in) wheelbase engineered for quick, flickable steering geometry. The 5.67-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
