RK 520 XRE Chain is designed as an OE-style replacement for mid-size motorcycles where riders want quick, smooth power delivery without sacrificing durability. Built using technology proven in on-road and off-road racing, this chain focuses on long wear life and consistent performance over time.
The key advantage is RK’s original double-X-shaped XW-Ring seal. It creates multiple lubricant pools (more than conventional O-ring designs) and helps keep lubricant locked in while keeping dirt and water out. Combined with vacuum-injected U-grease and tough nitrile butadiene rubber rings, the chain stays smoother for longer and reduces premature stretch—ideal for riders who demand reliability between services.

✅ Lightweight and durable construction for quick, smooth acceleration
