How to solve the chain noise issue on Suzuki GSX250R?

[Beckett]

The chain normally produces certain mechanical noise. Regular cleaning of the chain is recommended, along with applying appropriate lubricating oil. When riding on poor road conditions, maintenance should be more frequent; if individual chain links get stuck, thorough lubrication should be applied to restore flexibility.

I've been riding my Suzuki GSX250r for many years, and dealing with chain noise is quite simple—it's mainly due to dryness or excessive dirt on the chain. First, stop the bike and check the chain's condition; if it's too loose, it tends to jump and make loud noises, while if it's too tight, it accelerates wear. Loosen the rear wheel nut and adjust it to the middle position, allowing the chain to move about 20mm up and down, which is ideal. Cleaning is key—use a brush and chain cleaner to remove dirt, then spray and evenly apply a specialized lubricant. Maintain it weekly, and the noise will disappear. If the wear is severe, replace the chain and sprocket promptly—don't delay, as a broken chain mid-ride could lead to a crash. Safety comes first, and chain maintenance is a routine task—doing it yourself is both convenient and reliable.
