Built around Chang-Jiang's scooter motorcycle platform, the 2007 Chang-Jiang BD 150T 250 features a 250 cc (15.3 cu in) liquid-cooled single cylinder, four-stroke configuration. In factory specification, peak output is rated at 14.1 HP (10.3 kW) at 7,000 rpm, transferring power to the rear wheel through belt final drive. With a specific output of 56.4 HP per liter, the engine character is prioritizing low-RPM tractability, mechanical longevity and relaxed throttle response over peak redline numbers.
On the scales, the BD 150T 250 measures 175 kg (386 lbs) dry, translating to a power-to-weight ratio of 0.08 HP/kg (12.41 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,616 mm (63.6 in) wheelbase engineered for planted straight-line stability. The 10.5-liter (2.8 US gal) fuel tank paired with a rated consumption of 2.2 L/100 km provides an estimated theoretical range of roughly 477 km (296 miles) between fill-ups, while factory top speed is listed at 85 km/h (53 mph).

Power
Compare engine output with similar motorcycles if acceleration, highway use or two-up riding matters.
Weight
Compare weight carefully because it affects low-speed handling, parking and confidence.
Fuel Capacity
Fuel capacity helps estimate touring range and how often you may need to stop.
Brakes
Brake setup is worth comparing if you ride in traffic, mountains or with a passenger.
