The JT Brass Chain 525 Z3 Series X-ring is another variant of the motorcycle chain manufactured by JT Sprockets. This particular chain has a 525 pitch, which indicates the spacing between the chain's rollers. The pitch size is important to match the specifications of your motorcycle's sprockets.

Similar to the previous chain discussed, the JT Brass Chain 525 Z3 Series X-ring features the X-ring technology, providing superior sealing performance compared to traditional O-ring chains. The X-ring design reduces friction, enhances durability, and improves power transfer efficiency.

The "Brass" in the name refers to the color of the chain. Brass chains typically have a gold or silver appearance, giving them a distinctive look.

The length of the chain you mentioned is 120 links. The number of links determines the overall length of the chain and should be chosen according to your motorcycle's specific requirements. It is crucial to ensure that the chain length is compatible with your motorcycle's sprocket sizes and swingarm length.

When installing a new chain, it is essential to properly tension and adjust it to the manufacturer's specifications. Regular cleaning and lubrication are necessary for the chain's maintenance and longevity.

Always refer to your motorcycle's owner's manual or consult with a professional mechanic to ensure you select the correct chain size, pitch, and length for your specific motorcycle model.
