Engineered by Honda for the trial motorcycle segment, the 2010 Honda CRF450X 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 62.0 mm (3.8 x 2.4 inches) with a 12.0:1 compression ratio.
On the scales, the CRF450X measures 122 kg (269 lbs) wet (curb). Rider ergonomics and chassis geometry center around a 963 mm (37.9 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,478 mm (58.2 in) wheelbase engineered for balanced agility and highway composure. The 7.19-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
