At the heart of the 2016 Kawasaki KFX90 atv motorcycle, Kawasaki pairs a 89 cc (5.4 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 47.0 x 51.8 mm (1.9 x 2.0 inches) with a 10.0:1 compression ratio.
On the scales, the KFX90 measures 118.8 kg (262 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 650 mm (25.6 in) seat height — giving shorter riders and urban commuters confident flat-foot reach at traffic stops, combined with a 965 mm (38 in) wheelbase engineered for quick, flickable steering geometry. The 5.68-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
