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

Meet the EK 525 NX-Ring Super Heavy-Duty Gold Chain 124L — a purpose-built upgrade for riders who push their machines to the limit. With a rugged gold-coated finish and EK’s advanced NX-Ring sealing, this chain is engineered to endure dirty trails, brutal torque, and long rides without compromise.

NX-Ring technology for real-world durability

The innovative NX-Ring seals around each pin and roller, creating a robust barrier against dust, grit, and moisture. The result is less wear, smoother power transfer, and longer intervals between maintenance—so you can ride harder and service less often.

Gold finish: durability meets eye-catching style

Beyond its striking appearance, the gold coating provides an extra layer of corrosion resistance in challenging riding environments. It’s not just about looks; it’s about lasting performance in wet, muddy, or humid conditions.

Built for strength and precision

• 525 drive chain design for high-torque motorcycles and sport-focused builds
• 124-link length for flexible gearing and fitment with a wide range of sprockets
• Heavily engineered steel construction with heat-treated pins and rollers for reliability under load

Who benefits most from this chain

Why this chain stands apart

Unlike standard heavy-duty chains, the EK 525 NX-Ring combines a robust sealing system with a premium gold finish, delivering both longevity and a premium appearance.
