1989 Xingfu 250 A Technical Analysis & Specification Breakdown

Engineered by Xingfu for the classic motorcycle segment, the 1989 Xingfu 250 A relies on a 249 cc (15.2 cu in) air-cooled single cylinder, two-stroke powerplant. In factory specification, peak output is rated at 10 HP (7.3 kW) at 4,500 rpm, transferring power to the rear wheel through a 4-speed gearbox and chain final drive. With a specific output of 40.2 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 250 A measures 135 kg (298 lbs) wet (curb), translating to a power-to-weight ratio of 0.07 HP/kg (13.5 kg per horsepower). The 14-liter (3.7 US gal) fuel tank supports practical everyday commuting and weekend road stints, while factory top speed is listed at 110 km/h (68 mph).
