Positioned in Honda's enduro - offroad motorcycle lineup, the 2009 Honda CRF450R features a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 50.7 HP (37 kW) at 9,000 rpm while maximum torque reaches 46.9 Nm (34.6 lb-ft) at 7,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 112.9 HP per liter and a 2,000 rpm working window between peak torque (7,000 rpm) and peak power (9,000 rpm), the engine character is reflecting a performance-oriented street tune that balances strong mid-range pull with an energetic top-end rush.
On the scales, the CRF450R measures 118 kg (260 lbs) wet (curb), translating to a power-to-weight ratio of 0.43 HP/kg (2.33 kg per horsepower). 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 1,489 mm (58.6 in) wheelbase engineered for balanced agility and highway composure. The 7.2-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
