The number of sprocket teeth is one of the important parameters that affect the performance of motorcycle.

The number of sprocket teeth is one of the important parameters that affect the performance of motorcycle. According to the motorcycle, the more front gear teeth, the speed will be reduced, because the motorcycle is a fixed output power. When the number of teeth in the front disk is fixed, the more teeth in the back disk, the stronger the start, and the lower the tail speed; The smaller the number of teeth in the posterior disk, the weaker the start and the higher the tail speed. Motorcycle size sprocket teeth are generally very different, the small sprocket is the driving wheel, the general number of teeth is 13-15 teeth, the large sprocket for the driving wheel teeth is generally 30-50 teeth, the number of large sprocket teeth will be more, so that you can improve the output torque to help escape. When the sprocket is modified, the number of small sprocket teeth is increased or the number of large sprocket teeth is reduced, which can increase the speed at the same engine revolution, but the corresponding output torque will also reduce the acceleration. Under normal circumstances, under the premise of the same size of the front sprocket, the larger the rear sprocket, the stronger the vehicle's power performance will be, and the speed will be slower, and if the rear sprocket becomes smaller, the vehicle's power performance will be weakened, and the speed will be improved.

In addition, the number of teeth: small sprocket gear should not be too small, generally z≥17, the number of sprocket teeth is generally odd. Pitch: Choose a chain with a small distance as much as possible, and the effect of choosing a multi-row chain with a small distance will be better when overloaded. Center distance: the center distance of chain drive is too small, then the package Angle on the small sprocket is small, and the number of teeth of the sprocket is small. If large, it is easy to make the chain shake. Roller chain marking: Roller chain is a standard part, by the chain number - row number - number of chain standard... The motorcycle is also a 428 chain.
