1. Frame

The most important thing about the car body is the big frame. It can be said that everything in the car depends on the quality of the frame. Because all the components are installed on the frame, the engine is not good enough if the frame is not good.

1 The frame that has not been refurbished is more reliable because the paint can cover many real situations. So even if the frame has a slight scratch, it is better than those who repaint.

2 Carefully touch the surface of the frame to see if there are any irregularities. Or carefully observe the surface of the aluminum frame (the original color) is not different in gloss, if the gloss is different, it is probably polished.

3 The frame straight through tube has no traces of repair welding. If it is found that the welding on both sides of the straight-through part is inconsistent, then it is likely to be replenished. But this is a rare situation, and if it is, it will be a very serious accident car.

2. engine

The engine is to watch the second ride. At first glance, it is necessary to look at the place where there is no oil seepage outside, and whether there is any place to make up. In general, an engine that has not been moved is unlikely to seep oil, so oil seepage can also be considered as a dismantled representation. As long as it is a side cover and heat sink, as well as a water tank. The heat sink is inconsistent with the other ones. The color and appearance are different from the original ones. If you look carefully, you can see the difference. And if you make up, you must have traces of soldering. If you ride, you should pay attention to shifting, temperature, throttle response, and sound conditions. The shift must be smooth, the temperature can not be stretched, the throttle should be free and easy, the sound should be harmonious, there must be no clutter.

3. Braking System

This is a matter of life! Many cars have no problem in this respect, that is, they must be stressed enough, but they are relatively light. When you open it, try to see if it works well and normal, so that life is guaranteed.

4. Suspension system

The suspension system is the medium for communication between the driver and the road. Do you have to look at the oil spill? Is there a damping effect? It is best to check with the written look to see if there is any difference, so that you can avoid buying a barbaric assembly car, because the front suspension can not be replaced casually. There are also adjustments that must be used to see if there is any function.

5. Control system

Whether the handle is deformed or not, and whether the pedal is balanced or not is a factor that will affect daily driving in the future.

6. Surrounding and exterior parts

Be sure to check if all are original, and the exterior parts such as guards and turn signals should be checked carefully.
