• 
  NX-Ring sealed links provide superior sealing on both sides of the rollers, dramatically reducing dirt ingress and minimizing friction. The result is smoother operation, cooler running, and longer wear under wet, dusty, or muddy conditions.
• 
  Super H/Duty construction uses premium materials and precise heat treatment to endure high-torque applications, delivering repeatable performance under aggressive acceleration and sustained gravel-to-glass shifts.
• 
  Vibrant blue coating isn’t just cosmetic—it's a durable finish designed to resist corrosion and hold up against the elements, so your chain looks sharp ride after ride.
• 
  124-link length designed to fit a wide range of 525 sprocket configurations, providing robust engagement and consistent power delivery across gears for dependable acceleration and smooth cruising.
• 
  Engineered for longevity with hardened pins and rollers and tight tolerances, this chain is built to resist stretching and wear, keeping tension stable and sprockets aligned longer than standard setups.

Who is this for

Ideal for riders who demand a durable, high-performance chain for daily road use, weekend track days, and light-to-moderate off-road excursions. If you push your bike with quick shifts, aggressive throttle, or carry a bit more load on longer rides, the EK 525 NX-Ring is designed to handle those challenges with confidence.

Use cases and benefits

• 
  Track and sport riding: maintains consistent power transfer and reduced drag for quicker laps and smoother launches.
• 
  Wet or muddy conditions: sealed design protects internals, extending life in challenging weather.
• 
  Daily commuting and touring: dependable performance and a striking look that stands out on any bike.

Why choose EK 525 NX-Ring over alternatives — The NX-Ring system delivers superior sealing and lower friction compared to standard non-sealed chains, translating to longer service intervals, steadier tension, and better overall durability in real-world riding scenarios. The blue finish adds a distinctive aesthetic while offering practical corrosion resistance, making the chain not only resilient but also visually bold.

Maintenance tips for maximum longevity: regularly inspect chain wear and tension, clean off grit after riding in wet or dusty conditions, re-lubricate with a quality motorcycle chain lubricant, and replace the chain when elongation exceeds the manufacturer’s specification. Pair with compatible 525 sprockets to ensure optimal meshing, smooth operation, and extended chain life.
