If the chain or motorcycle sprocket is not properly matched, it will affect the performance and comfort of the engine.
1. The material of the sprocket is not easy to cause wear. The general sprocket is made of 45# steel, and the hardness is HRC 40-45. The chain is heat treated to increase the surface hardness.
2. The change of the transmission ratio of the front and rear sprocket should be determined according to the road condition of the car you drive. If you are driving on the flat road in the town, the chain transmission ratio can be reduced, which can improve the speed and acceleration performance.
