EK 525 O-Ring Chain 124L (10)

EK 525 O-Ring Chain 124L — Pack of 10 is a purpose-built drivetrain upgrade for riders who demand long life, consistent performance, and lower maintenance from their motorcycle chain.

Engineered around the 525 pitch (0.625 inches) and a sturdy 124-link length per chain, these chains are sealed with O-rings to lock in lubricant while fending off dirt and moisture. That means quieter operation, smoother acceleration, and fewer adjustments between rides—even in challenging weather.

Why choose an O-ring chain?

Unlike plain roller chains, O-ring seals create a protective barrier around the pins and rollers. The result is reduced chain stretch, slower wear on sprockets, and a drivetrain that stays responsive over longer intervals between tune-ups. EK uses robust materials and precision manufacturing to ensure each link remains consistent from the first mile to the last.

Performance and maintenance tips

• Lubrication: For optimal lifespan, re-lubricate after the first 500 miles (or per your maintenance schedule) and re-check tension regularly.


• Cleaning: Wipe chains after wet or muddy rides to minimize grit buildup before re-lubing.


• Tensioning: Maintain correct chain slack per the motorcycle’s service manual to ensure smooth shifting and reduce sprocket wear.


• Inspection: Look for stiff links, kinks, or obvious wear; replace chain and sprockets together when wear is evident.
