The EK 520 SRO6 O-Ring Chain is designed for dirt bikes, ATVs, and street motorcycles that require dependable drivetrain performance in demanding riding conditions. This 88-link chain uses a 520-size fitment and is identified by manufacturer part number 520SRO6-88. It is manufactured in Japan by EK and supplied under vendor part number 69-26288.
High-quality O-ring seals help retain lubricant inside the chain while limiting the entry of water, mud, and other contaminants. This construction supports consistent operation and extended service life across off-road and street applications. Solid rollers and enhanced anti-kink bushings further improve durability, helping the chain handle repeated load cycles and challenging riding environments.
For secure assembly, the EK 520 SRO6 features Japanese-made construction with quad-staked pin riveting into the side plates. This design promotes reliable chain integrity when properly installed and maintained. Confirm the 520 chain size, 88-link length, and motorcycle or ATV application before installation, and follow the vehicle manufacturer’s specifications for sprocket compatibility, adjustment, lubrication, and replacement.
