1. For domestically produced knock-off machines, look for appearance stickers, trademark LOGO letters and sticker defects, and machine number stickers on the rack.

2. Travel models: 2-stroke or 4-stroke models with less than 60 horsepower, especially the most popular models, such as F9.9.

3. Domestic assembly machines: They are generally second-hand machines, and the price is 30-50% off brand new ones, which is very attractive. Some parts are replaced with domestic ones or some parts are old parts.

Extended information:

1. First of all, the engine of the genuine product is 4CW, while the fake one is GY6. There are also some copycat cars using the 4CW engine produced by Feiying.

2. The genuine car has only one shock absorber, the knock-off has two, and some knock-off cars have only one shock absorber.

3. The genuine one has Yamaha on the frame nameplate, but the fake one does not.

4. What is written on the certificate of authenticity of the genuine product is that the Yamaha imported Swift Eagle generally has a single shock absorber without modification, while the domestically produced ones have dual shock absorbers. If the exhaust is modified It will definitely consume more fuel than the original one.

5. The characteristics of Yamaha scooters: when you get on the scooter and hit the accelerator hard, the front of the scooter will tilt up. This is because Yamaha scooters accelerate quickly, and the sound of the engine is mostly loud and impure. It’s just a lie. The new Yamaha Sound Eagle has a small and pure sound.
