Positioned in Yamaha's cross - motocross motorcycle lineup, the 2011 Yamaha YZ450F 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 97.0 x 60.8 mm (3.8 x 2.4 inches) with a 12.5:1 compression ratio.
On the scales, the YZ450F measures 111.1 kg (245 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 998 mm (39.3 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,491 mm (58.7 in) wheelbase engineered for balanced agility and highway composure. The 6.17-liter (1.6 US gal) fuel tank supports practical everyday commuting and weekend road stints.
