Engineered by Haojin for the sport motorcycle segment, the 2020 Haojin Taurus HJ125-22 utilizes a 125 cc (7.6 cu in) air-cooled single cylinder, four-stroke layout. In factory specification, peak output is rated at 10.5 HP (7.6 kW) at 8,500 rpm while maximum torque reaches 9.8 Nm (7.2 lb-ft) at 7,500 rpm, transferring power to the rear wheel through chain final drive. With a specific output of 84 HP per liter and a 1,000 rpm working window between peak torque (7,500 rpm) and peak power (8,500 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 Taurus HJ125-22 measures 115 kg (254 lbs) dry, translating to a power-to-weight ratio of 0.09 HP/kg (10.95 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,300 mm (51.2 in) wheelbase engineered for quick, flickable steering geometry. The 14-liter (3.7 US gal) fuel tank paired with a rated consumption of 2.5 L/100 km provides an estimated theoretical range of roughly 560 km (348 miles) between fill-ups, while factory top speed is listed at 85 km/h (53 mph).
