2020 Haojue KA 150 Technical Analysis & Specification Breakdown
At the heart of the 2020 Haojue KA 150 sport motorcycle, Haojue features a 149 cc (9.1 cu in) air-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 11.1 HP (8.1 kW) at 8,000 rpm while maximum torque reaches 11.4 Nm (8.4 lb-ft) at 6,000 rpm. With a specific output of 74.5 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.
