NX 650 Dominator

2003 Honda NX 650 Dominator Technical Analysis & Specification Breakdown

Engineered by Honda for the enduro - offroad motorcycle segment, the 2003 Honda NX 650 Dominator relies on a 644 cc (39.3 cu in) single cylinder, four-stroke powerplant. In factory specification, peak output is rated at 41 HP (29.9 kW) at 6,000 rpm while maximum torque reaches 51 Nm (37.6 lb-ft) at 5,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 63.7 HP per liter and a 1,000 rpm working window between peak torque (5,000 rpm) and peak power (6,000 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 NX 650 Dominator measures 167 kg (368 lbs) dry, 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 880 mm (34.6 in) seat height — reflecting a long-travel chassis stance that favors ground clearance and off-pavement control. The 16-liter (4.2 US gal) fuel tank supports practical everyday commuting and weekend road stints.
