EK 525 NX-Ring Super H/Duty Green Chain 124L (10)

Meet the EK 525 NX-Ring Super Heavy Duty Green Chain 124L (10) — the workhorse upgrade for riders who demand relentless durability, unwavering performance, and a touch of bold style on every ride. Built around a true 525-pitch drive system and 124 links, this chain is engineered to withstand brutal riding conditions—from gnarly enduro trails to high-velocity track days and hard-pulling street rides.

Why the EK 525 NX-Ring stands out

• 
  NX-Ring sealing technology — a precision-sealed design that minimizes friction, keeps lubrication in, and shrugs off mud, water, and grit. The result is smoother power transfer, reduced wear, and longer interval periods between maintenance.
• 
  Green color seals — not just for style. The distinctive green seals make wear and life-cycle monitoring easier, so you know when it’s time to inspect or replace damping components and sprockets.
• 
  Super Heavy Duty construction — built for high-torque applications and aggressive riding. Hardened pins, robust plates, and tightly engineered tolerances deliver impressive resistance to elongation and bending under load.
• 
  525 pitch, 124 links — a standard, reliable fit for a wide range of MX, enduro, and street bikes that rely on a 525 drivetrain. The 124-link length provides flexibility for precise chain-line setup and compatibility with common rear sprocket configurations.
• 
  Longer service life with less maintenance — optimized lubrication retention and sealed seals help your chain stay quieter, cleaner, and ready for more miles between top-ups.

Who should consider this chain

Ideal for riders who push their machines hard—off-road adventurers, track-day veterans, and everyday riders who value reliability. If you ride a motorcycle with a 525-pitch drivetrain and you want a chain that delivers consistent performance under heavy loads, the EK 525 NX-Ring is a compelling choice.

Use cases and benefits

• 
  Off-road and enduro: keeps a steady supply of power to the rear wheel in rough terrain, with seals that resist sand and mud intrusion.

  Daily commuting with a performance edge: reduced maintenance overhead while preserving chain life and riding quality.

Installation and care tips

For best results, pair the EK 525 NX-Ring with compatible EK sprockets and maintain proper chain tension to avoid excess wear. Regularly inspect for elongation, check lubrication levels, and clean the chain to maximize seal life. Consider a periodic re-lubrication interval aligned with riding conditions and mileage. Professional installation is recommended if you’re unsure of the correct chain length or derailment-free alignment.

Experience the difference a purpose-built, heavy-duty chain makes in how your bike delivers power, handles torque, and endures demanding rides. The EK 525 NX-Ring Super Heavy Duty Green Chain 124L (10) bundles premium performance with a durable, reliable drivetrain—ready to take on your next adventure.
