525RX Sealed Chain
seal chain structure
| Pin | The link connecting the outer links is the central axis of the chain bend. |
| Bushing | The chain plate connected to the inside is the supporting force axis of the pin shaft. |
| Roller | Contact with the sprocket to make the chain roll smoothly. |
| Inner/outer chain link | Together with the pin, it supports the transmission of load and power. |
| Seal Ring | Lubricating grease sealed between the pin and the bushing. |
| lubricating oil | Provide lubrication between pins and bushings to prevent wear and elongation. |

The Importance of X-Rings
Unlike standard O-ring chains, RX rings are designed to reduce drag. Their shape reduces contact with the chain plates, which reduces resistance as the chain moves. At the same time, it seals in lubricant more effectively. This combination helps your bike deliver power more efficiently and keeps your chain cleaner over longer rides.
525RX Motorcycle Chain
The 525RX chain is a drive chain designed for motorcycles. “525” is a term referring to the pitch. This chain is usually found on motorcycles with a displacement of 250cc and above. Its unique feature is the “RX ring” design.

Frequently Asked Question
This is a technical term for the size code of the chain. The “5” refers to the pitch (5/8 inch, the distance between the pins) is 5/8 inch. The “25” refers to the width between the inner teeth, which is 5/16 inch (about 8 mm) to be exact. This is a very common specification for medium and large motorcycles.
The shape of the RX ring is designed to reduce friction and seal grease at the same time. It will last longer and run smoother, especially under stress.
If it is properly maintained and used normally, it can last 15,000 miles or more. Of course, regular cleaning and lubrication will help its life a lot.
The gold finish is not just for aesthetics – it helps prevent the chain from rusting and corroding.
The gold color is not only for aesthetics, but also for preventing the chain from rusting and corrosion.
Of course not, these chains are only suitable for medium to large motorcycles (250cc and above). Please check the vehicle manual carefully and read it carefully when installing to determine whether this chain is suitable for your vehicle.
Even sealed chains need to be oiled and checked regularly, and chain lubricant should be added every 300-600 miles. If riding in the rain or on dusty roads, oiling needs to be done more frequently.
