Engineered for the demanding world of motocross, the EK 520 H/Duty Motocross Orange Chain 120L (10) delivers relentless strength, precise power transfer, and eye-catching visibility wherever you ride. The vibrant orange finish isn’t just style — it’s a practical cue for quick wear inspections and tension checks between sessions.

• 
  Heavy-duty 520 chain design built to handle high-torque launches, aggressive braking, and rough track conditions typical of motocross, enduro, and sprint races.


• 
  120 links length sized to fit a wide range of 520-sprocket setups; includes a standard master link for easy installation and adjustment. Sold as a 10-pack for teams or riders who want spare chains on hand.


• 
  Durable construction forged from high-strength alloy steel with heat-treated pins and bushings to resist wear, stretch, and impact from jumps and hard landings.


• 
  Sealed, low-friction operation designed to minimize dirt intrusion and maximize life in dusty, muddy race environments, while delivering smooth, predictable power delivery.


• 
  High-visibility orange finish makes inspection, tension checks, and chain alignment faster during pit stops and maintenance.

This EK 520 H/Duty chain is ideal for riders who demand reliability in extreme riding conditions—riders who race locally, participate in track days, or push their bikes through rough terrain. It’s a practical upgrade over standard chains, delivering longer service life, easier maintenance, and consistent performance session after session.

Use cases and tips: Use on bikes with 520 chain systems; ensure correct sprocket count and chain length; after installation, break in at moderate speeds before hitting full power; clean and lube after rides in dusty conditions; recheck tension after the first few laps and periodically thereafter to maintain optimal drive efficiency.

Choosing EK means opting for a chain engineered for motocross reliability, with visible orange aesthetics for quick checks and a design that holds up to mud, dust, and aggression of off-road riding. If you’re building a race-ready setup or stocking spare parts for a team, the 120L (10) pack keeps you prepared to stay in the race longer.
