The RK 525 XRE drive chain is designed for OE replacement on mid-size motorcycles requiring dependable 525-size chain performance. With 112 links and a high-tensile construction, this chain supports reliable power transfer, smooth acceleration, and consistent operation in both on-road and off-road applications. The RK 525XRE-112 is engineered using technology developed through demanding racing environments, making it a practical choice for riders seeking durable replacement performance.
RK’s original double-X-shaped XW-Ring seal helps extend chain wear life by providing three lubricant pools, offering greater lubricant retention than conventional O-ring designs. Specially formulated vacuum-injected U-grease is locked inside the seal by tough nitrile butadiene rubber XW-Rings, helping protect internal components from contamination while reducing maintenance demands. Polished and shot-peened link plates contribute to smooth operation and dependable tensile strength.
This RK chain is suitable for compatible mid-size motorcycles using a 525 drive-chain system. Confirm the motorcycle manufacturer’s application requirements, chain size, and required link count before installation. The chain includes a rivet connecting link for secure assembly when installed with the appropriate chain riveting tool and according to the motorcycle manufacturer’s service procedures.
