1.5.2 Motorcycle Chain Transmission
Application Examples Motorcycles are high-speed applications that operate in tough conditions— rain, dirt, sand, and high shock loads. These specially developed chains are used as the part of the drive train to transmit the motor power to the back wheel (Figure 1.19). Motorcycle Chains are superior to gears, which are in the crank cases, by the ease in adjusting the shaft center distance and the number of teeth of the sprocket. Therefore, you can freely design the motorcycle’s reduction ratio taking into account the specifications and the working conditions. In the case of a racing motorcycle, for example, the engine power may be 180 hp, and the chain speed is 1,500 m/min.

Construction and Features Motorcycle Chains have the same basic construction and sizes (numbers 40, 50, and 60, Table 1.9) as Standard Roller Chains. But they have a special width of inner links. Because of the very demanding working conditions, some
