Engineered by Kawasaki for the cross - motocross motorcycle segment, the 2012 Kawasaki KX 450F Leo Vince pairs a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. Internal engine geometry specifies a bore and stroke of 96.0 x 62.1 mm (3.8 x 2.4 inches) with a 12.5:1 compression ratio.
On the scales, the KX 450F Leo Vince measures 113 kg (249 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 960 mm (37.8 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,481 mm (58.3 in) wheelbase engineered for balanced agility and highway composure. The 6.2-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
