How to choose a motorcycle

1. The quality of the engine is the key to determining the quality of the motorcycle. When choosing, first observe whether the engine and the frame are on the same centerline, and then step on the starter lever in neutral. If no sound is heard, it means that the engine cylinder is OK. Turn on the power supply, turn on the fuel tank switch, and start the engine locally. Check the engine starting and gear shifting. A good engine can be started by pressing the starter shift lever 2-3 times, and it does not turn off at idle speed, and there is no noise. At the same time, the acceleration is very sensitive. . Afterwards, the gear shift inspection was carried out, and the gears were shifted from low gear to high gear step by step. The gear shift was smooth, the gears of each gear did not collide when shifting, and the exhaust pipe nut had no air leakage, even if the quality was good. Finally, observe the color of the smoke emitted by the muffler, light cyan is the best.

2. The appearance of the car body. The layout is required to be reasonable, novel and beautiful, smooth and bright. The front and rear shock absorbers should be parallel and symmetrical with the front and rear tires, and all kinds of accessories and parts are required to be complete. In addition, the quality of painting and electroplating parts is not only the main factor in determining the beautiful appearance, but also plays a role in protecting the parts and reducing wear. The appearance of spray-painted spare parts requires that the paint surface be uniform, bright, and have no bumps.

3. Operating mechanism. The control mechanism includes many aspects, mainly the steering handle, clutch handle, throttle wire handle, front and rear brake devices and other components should be checked. It is required that the elastic force on both sides of the front and rear shock absorbers is uniform and the same, the steering handle is flexible and reliable, the clutch handle and the throttle wire handle can rotate freely, and the front and rear brakes are safe and reliable (the return position must be returned to the original position).

4. Electrical equipment. Check the working conditions of the headlights, direction lights, brake lights, instrument lights and the sound of the horn one by one. If there is no abnormality, it means that the electrical appliances are normal. In addition, you can take the car back and forth a few times, and it feels light to be a good car. On the contrary, some parts encounter friction and resistance. It is also necessary to observe whether the front and rear shock absorbers and the engine have oil leakage, and whether the ride is comfortable.
