At the heart of the 2017 Kawasaki KX85-II cross - motocross motorcycle, Kawasaki relies on a 84 cc (5.1 cu in) liquid-cooled single cylinder, two-stroke powerplant. Internal engine geometry specifies a bore and stroke of 48.5 x 45.8 mm (1.9 x 1.8 inches) with a 10.9:1 compression ratio.
On the scales, the KX85-II measures 77 kg (170 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 870 mm (34.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,310 mm (51.6 in) wheelbase engineered for quick, flickable steering geometry. The 5-liter (1.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
