In the entire mechanical structure of a motorcycle, the chain plays a very important part - power transmission. Basically, the role of the chain is no less than that of the engine, clutch, and brake caliper.

At present, the chains on the market are commonly classified into oil-sealed chains and non-oil-sealed chains: the so-called oil-sealed chain means that there is an oil seal between the inner and outer chain pieces, and the lubricating oil is wrapped in the middle to help the chain lubricate. Without this oil seal, it is called a non-oil seal chain.

Based on the above structure, if the chain is not maintained for a long time, the lubrication effect is not good, it will generate greater frictional resistance during operation, and there will also be a certain loss of engine power. Long-term uneven operation may also cause the chain to loosen or even fall off. Therefore, the chain needs to be decontaminated and lubricated regularly.

The general maintenance cycle is once every 300-500 kilometers. Use a special chain cleaner to clean the chain, and then spray the chain oil to maintain the sealing and elasticity of the oil seal. It is also recommended to carry chain maintenance equipment for long-distance riding for regular cleaning and maintenance chain.
