Positioned in Honda's enduro - offroad motorcycle lineup, the 2017 Honda CRF450X utilizes a 449 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 44.5 HP (32.5 kW) at 7,500 rpm while maximum torque reaches 41.3 Nm (30.5 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 99.1 HP per liter and a 500 rpm working window between peak torque (7,000 rpm) and peak power (7,500 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 CRF450X measures 122 kg (269 lbs) wet (curb), translating to a power-to-weight ratio of 0.36 HP/kg (2.74 kg per horsepower). 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 1,481 mm (58.3 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.
