Positioned in Chang-Jiang's classic motorcycle lineup, the 1998 Chang-Jiang CJ750 M1M features a 746 cc (45.5 cu in) air-cooled twin, four-stroke configuration. In factory specification, peak output is rated at 23.7 HP (17.3 kW), transferring power to the rear wheel through a 4-speed gearbox and shaft drive (cardan) final drive. With a specific output of 31.8 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 CJ750 M1M measures 360 kg (794 lbs) dry, translating to a power-to-weight ratio of 0.07 HP/kg (15.19 kg per horsepower). Rider ergonomics and chassis geometry center around a 1,420 mm (55.9 in) wheelbase engineered for balanced agility and highway composure. The 22-liter (5.8 US gal) fuel tank paired with a rated consumption of 7 L/100 km provides an estimated theoretical range of roughly 314 km (195 miles) between fill-ups, while factory top speed is listed at 90 km/h (56 mph).
