Built around Chang-Jiang's classic motorcycle platform, the 2010 Chang-Jiang Dong Tian 750 features a 746 cc (45.5 cu in) air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 22 HP (16.1 kW) at 5,000 rpm, transferring power to the rear wheel through a 4-speed gearbox and shaft drive (cardan) final drive. With a specific output of 29.5 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 Dong Tian 750 measures 371 kg (818 lbs) wet (curb), translating to a power-to-weight ratio of 0.06 HP/kg (16.86 kg per horsepower). The 24-liter (6.3 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 90 km/h (56 mph).
