The EK 520RV3D-120C chain is a 520 Series roller chain designed for powersports applications requiring dependable drive performance and extended wear resistance. This chain features an RV3D configuration with NX2 ring seals, providing a durable barrier against dirt, moisture, and lubricant loss while helping protect internal components during demanding riding conditions.
Manufactured by EK and supplied under vendor part number 693-1020C, this chain includes 120 links and is intended for compatible 520 chain drive systems. Its sealed construction helps reduce maintenance requirements compared with non-sealed chain designs, making it suitable for street, sport, touring, off-road, and other applications where consistent power transfer and durability are important.
Verify vehicle fitment before installation by matching the manufacturer’s chain specification, pitch, link count, sprocket compatibility, and required chain style. The EK 520RV3D-120C is a replacement chain component and may require link adjustment or additional installation hardware depending on the application. Proper installation, lubrication, tension adjustment, and routine inspection are recommended for optimal service life.
