Positioned in Kawasaki's atv motorcycle lineup, the 2009 Kawasaki Brute Force 650 4x4i pairs a 633 cc (38.6 cu in) liquid-cooled v2, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 80.0 x 63.0 mm (3.1 x 2.5 inches) with a 9.9:1 compression ratio.
On the scales, the Brute Force 650 4x4i measures 296.6 kg (654 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 904 mm (35.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,285 mm (50.6 in) wheelbase engineered for quick, flickable steering geometry. The 20.43-liter (5.4 US gal) fuel tank supports practical everyday commuting and weekend road stints.
