Positioned in Honda's cross - motocross motorcycle lineup, the 2009 Honda CRF450F features a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke configuration. Internal engine geometry specifies a bore and stroke of 96.0 x 62.1 mm (3.8 x 2.4 inches) with a 12.0:1 compression ratio.
On the scales, the CRF450F measures 106.5 kg (235 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 955 mm (37.6 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 5.67-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
