RK 520 XRE is a lightweight, durable sealed drive chain designed for smooth acceleration and long service life on mid-size motorcycles. Its original double-X “XW-Ring” seal keeps lubrication locked in for consistent performance.
The RK 520 XRE drive chain is built for riders who want a strong OE-style replacement with modern racing-derived durability. Thanks to RK’s original double-X-shaped XW-Ring seal design, the chain retains lubrication more effectively than conventional O-ring chains—helping reduce friction, slow down wear, and keep power delivery smooth over long mileage.
Whether you ride on-road or off-road, the 520 XRE is engineered to deliver quick, consistent acceleration with reliable strength. Polished and shot-peened link plates add durability under load, while the vacuum-injected U-grease is locked in by tough nitrile butadiene rubber seals for long-lasting performance in demanding conditions.
