What's the difference between Feizhi 150 and Feizhi 250?

Like cars, engine displacement is also the main basis for classifying models. The greater the engine displacement, the greater the power, the higher the manufacturing cost and the higher the technical content. This is the basic law. The engine of Feizhi 250 is cooled by air oil, and the piston is made of forged aluminum alloy, which is light in weight and small in moment of inertia, which is beneficial to reducing engine vibration, improving comfort, speeding up and power output. The cylinder wall adopts imported electroplating ceramic technology, complete sets of imported EFI system and auxiliary equipment such as sensors and throttle valves. The Feizhi 150 engine does not adopt these advanced technologies. Although it is also a good engine, it is still not as good as Feizhi 250.
