Positioned in Kawasaki's cross - motocross motorcycle lineup, the 2008 Kawasaki KX100 pairs a 99 cc (6 cu in) liquid-cooled single cylinder, two-stroke architecture with road-focused gearing. In factory specification, maximum torque reaches 40 Nm (29.5 lb-ft) at 11,500 rpm, transferring power to the rear wheel through a 6-speed gearbox and chain final drive. Internal engine geometry specifies a bore and stroke of 52.5 x 45.8 mm (2.1 x 1.8 inches) with a 9.6:1 compression ratio.
On the scales, the KX100 measures 68 kg (150 lbs) dry. 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 1,290 mm (50.8 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.
