Built around Kawasaki's cross - motocross motorcycle platform, the 2010 Kawasaki KX 85 Monster Energy 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 10.0:1 compression ratio.
On the scales, the KX 85 Monster Energy measures 69 kg (152 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 841 mm (33.1 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams.
