At the heart of the 2020 Honda CRF450R cross - motocross motorcycle, Honda pairs a 449.7 cc (27.4 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 53 HP (38.7 kW) at 9,000 rpm while maximum torque reaches 48 Nm (35.4 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 117.9 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 112 kg (247 lbs) wet (curb), translating to a power-to-weight ratio of 0.47 HP/kg (2.11 kg per horsepower). Rider ergonomics and chassis geometry center around a 960 mm (37.8 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 6.43-liter (1.7 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 170 km/h (106 mph).
