2021 Honda CRF300RX Technical Analysis & Specification Breakdown

Engineered by Honda for the enduro - offroad motorcycle segment, the 2021 Honda CRF300RX pairs a 295.5 cc (18 cu in) liquid-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 27.3 HP (19.9 kW) at 11,300 rpm while maximum torque reaches 26.6 Nm (19.6 lb-ft) at 9,500 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 92.4 HP per liter and a 1,800 rpm working window between peak torque (9,500 rpm) and peak power (11,300 rpm), the engine character is indicating a tractable, stress-free state of tune focused on everyday usability and broad torque delivery.

On the scales, the CRF300RX measures 111 kg (245 lbs) wet (curb), translating to a power-to-weight ratio of 0.25 HP/kg (4.07 kg per horsepower). Rider ergonomics and chassis geometry center around a 957 mm (37.7 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control, combined with a 1,486 mm (58.5 in) wheelbase engineered for balanced agility and highway composure. The 7.3-liter (1.9 US gal) fuel tank supports practical everyday commuting and weekend road stints.
