EK 525 NX-Ring Super H/Duty Black with Gold Pin Rivet Link

EK 525 NX-Ring Super Heavy-Duty Black with Gold Pin Rivet Link is engineered for riders who demand torque, durability, and long service life from every mile. Built for mid- to large-displacement bikes, this 525 pitch chain combines rugged strength with advanced sealing to keep you moving when the going gets tough.

• 
  525 pitch motorcycle chain designed for bikes that rely on consistent power transfer, compatible with standard 525 sprockets for a wide range of street, sport, and adventure bikes.
• 
  NX-Ring sealed design employs dual-stage seals to minimize dirt ingress while preserving lubrication, reducing friction, heat buildup, and chain elongation under heavy loads.
• 
  Black oxide finish delivers enhanced corrosion resistance and a stealth, hard-wearing look that hides grime between cleanings.
• 
  Gold-pin rivet master link adds high-visibility, robust joining strength, making installation and future maintenance straightforward with the included rivet link.
• 
  Reinforced inner and outer plates offer greater tensile strength and wear resistance for demanding riding scenarios—from aggressive street launches to long-haul sessions on rough roads.

What this means for you is dependable power delivery that lasts longer under punishment. You’ll notice smoother throttle response, reduced chain stretch, and fewer interruptions from wear-related issues—kept through tougher riding conditions and easier maintenance cycles.

Who is it for?

• Riders who push high torque on street and sport bikes, including track days and spirited back-road sessions.
• Adventure and dual-sport riders facing mixed surfaces and harsher conditions where durability matters most.
• Owners who want a visually durable, low-maintenance drive chain that stands up to aggressive riding styles.

Installation and care tips

Install with a proper chain riveter and ensure the rivet link sits flush after installation. Regularly lubricate the chain with a high-quality motorcycle chain lube, and check tension according to your bike’s manual. Inspect sprockets and the chain for wear, and replace both as needed to maintain optimal power transfer and longevity.
