Introducing the 2015 Haojin HJ125-20A, a well-crafted sport motorcycle designed to capture the essence of urban riding while delivering an exhilarating experience. As a product from one of China’s emerging motorcycle manufacturers, Haojin aims to offer a blend of performance and affordability. This model is particularly appealing to entry-level riders and those seeking a nimble commuter bike that doesn’t compromise on style or capabilities. With its bold color options of red, black, blue, and orange, the HJ125-20A is sure to turn heads while navigating through city streets. At the heart of the HJ125-20A is a lively 124cc single-cylinder two-stroke engine, generating a respectable 10.46 horsepower and 8.80 Nm of torque at 7000 RPM. This powertrain, complemented by an efficient carburettor fuel system, offers a top speed of 85 km/h (52.8 mph) – perfect for zipping through traffic or enjoying a weekend ride. The motorcycle’s air cooling system ensures reliability in various conditions, while its fuel consumption of 2.10 liters per 100 km (an impressive 112.01 mpg) makes it incredibly economical for daily commutes. Whether you’re a new rider or someone looking for a lightweight machine that’s easy to handle, the HJ125-20A promises an engaging ride with a balance of responsiveness and control. The chassis of the HJ125-20A is designed for agility and comfort, featuring a single disc brake at the front and an expanding drum brake at the rear for dependable stopping power. Weighing in at just 113 kg (249.1 lbs), this bike is agile and easy to maneuver, ensuring that riders can handle it with confidence, even in tight spaces. Its compact dimensions (2064 mm long, 750 mm wide, and 1085 mm high) make it an ideal choice for navigating busy urban environments. The dual starting system—both electric and kick—adds a layer of convenience, allowing riders to choose their preferred method of ignition based on the situation. **

Pros

  • Fuel Efficiency: With a consumption rate of 2.10 liters/100 km, the HJ125-20A is a cost-effective option for daily riders.
