NK 150

2022 Haojue NK 150 Technical Analysis & Specification Breakdown

Built around Haojue's sport motorcycle platform, the 2022 Haojue NK 150 pairs a 149 cc (9.1 cu in) air-cooled single cylinder, four-stroke architecture with road-focused gearing. In factory specification, peak output is rated at 11.8 HP (8.6 kW) at 8,000 rpm while maximum torque reaches 11.6 Nm (8.6 lb-ft) at 6,000 rpm, transferring power to the rear wheel through a 5-speed gearbox and chain final drive. With a specific output of 79.2 HP per liter and a 2,000 rpm working window between peak torque (6,000 rpm) and peak power (8,000 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 NK 150 measures 139 kg (306 lbs) wet (curb), translating to a power-to-weight ratio of 0.08 HP/kg (11.78 kg per horsepower). Rider ergonomics and chassis geometry center around a 835 mm (32.9 in) seat height — resulting in a taller command-style riding posture suited to medium-to-tall inseams, combined with a 1,360 mm (53.5 in) wheelbase engineered for quick, flickable steering geometry. The 12.5-liter (3.3 US gal) fuel tank supports practical everyday commuting and weekend road stints.
