The RK 525 XRE drive chain is designed for OE replacement on mid-size motorcycles and delivers smooth, responsive power transfer for on-road and off-road applications. This 120-link chain is engineered with advanced technology developed through demanding racing environments, making it a dependable choice for riders seeking consistent acceleration and long service life.
RK’s original double-X-shaped XW-Ring seal helps extend chain wear life by retaining lubricant more effectively than conventional O-ring designs. Each XW-Ring creates three lubricant pools, helping protect the internal bearing surfaces from contamination while reducing friction during operation. The chain is lubricated with specially formulated vacuum-injected U-grease, which is secured by durable nitrile butadiene rubber XW-Rings.
Polished and shot-peened link plates improve strength and durability, while the chain’s high tensile strength supports reliable performance under demanding riding conditions. The RK 525 XRE includes a rivet connecting link for installation and is suitable for compatible mid-size motorcycles using a 525 chain specification. Always verify the motorcycle manufacturer’s recommended chain size, link count, and fitment before installation. Manufactured by RK, this chain is identified by manufacturer and vendor part number 525XRE-120.
