2009 Chang-Jiang 750 M1 Technical Analysis & Specification Breakdown

At the heart of the 2009 Chang-Jiang 750 M1 classic motorcycle, Chang-Jiang utilizes a 746 cc (45.5 cu in) air-cooled twin, four-stroke layout. In factory specification, peak output is rated at 22 HP (16.1 kW) at 4,700 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 750 M1 measures 350 kg (772 lbs) dry, translating to a power-to-weight ratio of 0.06 HP/kg (15.91 kg per horsepower). The 24-liter (6.3 US gal) fuel tank paired with a rated consumption of 7 L/100 km provides an estimated theoretical range of roughly 343 km (213 miles) between fill-ups, while factory top speed is listed at 90 km/h (56 mph).
