At the heart of the 2012 Honda CRF450R cross - motocross motorcycle, Honda 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 12.0:1 compression ratio.
On the scales, the CRF450R measures 108.9 kg (240 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 953 mm (37.5 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 5.68-liter (1.5 US gal) fuel tank supports practical everyday commuting and weekend road stints.
