Introducing the 2007 Chang-Jiang BD50QT-9 125, a scooter that embodies the perfect blend of practicality and personality. As part of the ever-expanding scooter market, this model is tailored for urban commuters and novice riders seeking an economical yet stylish mode of transportation. With its distinctive design and approachable price point, the BD50QT-9 125 stands out in the crowd of scooters, making it an excellent choice for those looking to navigate city streets with ease and flair. At the heart of the Chang-Jiang BD50QT-9 125 lies a robust 125cc single-cylinder, four-stroke engine that delivers a respectable 3.35 horsepower at 7,000 RPM. This power is coupled with a lightweight chassis, tipping the scales at just 97 kg (213.8 pounds), allowing the scooter to reach a top speed of 45 km/h (28 mph). The air-cooled engine is designed for efficiency, boasting an impressive fuel consumption of 1.90 liters per 100 km — equivalent to 123.80 mpg. Whether you're zipping through traffic or enjoying a leisurely ride, the BD50QT-9 provides a smooth and responsive experience, enhanced by a centrifugal clutch and belt final drive that ensure seamless acceleration. The Chang-Jiang BD50QT-9 125 doesn't skimp on features either. It comes equipped with both electric and kick starters for reliable ignition in any situation. Its braking system includes a single disc at the front and a reliable drum brake at the rear, ensuring confident stopping power. The scooter's dimensions — 1,955 mm in length, 700 mm in width, and standing 1,095 mm tall — provide a comfortable riding position, while a ground clearance of 120 mm makes it adept at tackling urban obstacles. With a fuel capacity of 6 liters (1.59 gallons), riders can enjoy extended journeys with fewer stops at the pump. **

Pros

  • Outstanding Fuel Efficiency: With a remarkable 123.80 mpg, the BD50QT-9 is budget-friendly for daily commutes.
  • Lightweight and Agile: Its low weight makes it easy to maneuver through crowded streets and tight spaces.
  • User-Friendly Features: The combination of electric and kick starters caters to both seasoned riders and newcomers alike.

Cons

  • Limited Power Output: With just 3.35 HP, it may not satisfy those seeking high-speed thrills or long-distance touring.
  • Basic Braking System: The drum brake at the rear may not provide the same level of performance as modern disc brakes.
  • Modest Top Speed: Capped at 45 km/h, it might not be suitable for riders looking to keep up with faster traffic.
