There are three main modes of motorcycle transmission：
Chain drive：for ordinary motorcycles, chain drive mode has these advantages:low cost, mature and reliable technology, convenient maintenance and maintenance and best practicality.
Shaft drive：the shaft transmission has higher manufacturing cost, higher requirement for material, and greater difficulty in processing. But it is simpler and more stable than chain drive if you use it properly.
Belt drive. This type of drive we often see in American cruise car large and scooter. The structure of the belt is very simple, the transmission is very smooth and soft, and it can play a very good buffer. The inner layer of the belt is designed as a sawtooth, which can better play the role of transmission. But subject to the material, the long belt will stretch and deform due to force and affect the transmission efficiency, so timing debugging and replacement is also essential.
