RK 520 XRE is a lightweight, durable sealed drive chain designed for smooth acceleration and long service life on mid-size motorcycles. Its XW-Ring (double X-ring) sealing retains lubricant better than conventional O-rings.
RK 520 XRE Chain is built for riders who want a reliable OE-style replacement with upgraded sealing technology and long wear life. Thanks to RK’s original double-X-shaped XW-Ring seal, the chain keeps lubrication where it belongs, helping reduce friction and stretch for consistently smooth power delivery.
If your current chain is wearing quickly, getting tight spots, or losing smoothness under load, the 520 XRE is designed to improve durability and acceleration feel. It’s developed using racing-derived know-how for both on-road and off-road use, with polished and shot-peened plates for dependable performance.
