2012 Kawasaki KX85 II Technical Analysis & Specification Breakdown
Engineered by Kawasaki for the cross - motocross motorcycle segment, the 2012 Kawasaki KX85 II utilizes a 84 cc (5.1 cu in) liquid-cooled single cylinder, two-stroke layout. Internal engine geometry specifies a bore and stroke of 48.5 x 45.8 mm (1.9 x 1.8 inches) with a 10.0:1 compression ratio.
On the scales, the KX85 II measures 70 kg (154 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 1,290 mm (50.8 in) wheelbase engineered for quick, flickable steering geometry. The 5.5-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
