EK 520 O-Ring Chain 120L (10)

EK 520 O-Ring Chain 120L — engineered for riders who demand stamina, precision, and reliability from every mile. Built for 520-series drivetrains, this 120-link chain delivers smooth, consistent power transfer with every twist of the throttle, whether you’re cruising highway lanes or exploring winding back roads.

In this 10-pack, you get ten complete 120-link chains, giving you long-term confidence for maintenance on a single bike or for stocking up across a small fleet. The EK 520 O-Ring chain uses sealed O-rings to trap lubrication inside the link and resist dirt, grime, and water from infiltrating the pin and roller joints. That design translates to less chain stretch, reduced wear, and extended life even in demanding riding conditions.

• 
  O-ring sealed joints: keep lubrication in and contaminants out, dramatically reducing wear and extending chain life.
• 
  120 links per chain: compatible with common 520-series sprockets, providing reliable fit and optimized power delivery.
• 
  Durable construction: robust pins and rollers with heat-treated components resist stretching and fatigue under high torque.
• 
  Low-friction performance: optimized internal geometry and sealed joints minimize power loss, ensuring crisp throttle response and smoother gear changes.
• 
  Corrosion resistance: protective plating helps maintain durability and appearance in wet or salty-road riding conditions.
• 
  Maintenance-friendly: while O-rings reduce frequent lubrication needs, periodic cleaning and proper tensioning maximize life and performance.

Ideal for: riders who push their motorcycles with spirited riding, long commutes, or regular off-road sessions where the chain faces dirt, mud, and moisture. This 10-pack is a practical choice for workshop kits and service shops that service multiple bikes with a 520-chain-drive.

Care and installation tips: use a compatible chain tool or rivet method to join the chain, set tension according to your bike’s manual, and inspect wear with a chain gauge. For best results, clean the chain and sprockets before installation and apply a light protective lubricant after installation if you ride in dusty or wet environments.

What you get: 10 x EK 520 O-Ring Chains, each 120 links long, ready to install on compatible 520-drive motorcycles or ATVs. Before installing, verify sprocket compatibility and chain pitch to ensure optimal performance and longevity.
