The EK 525 SRX2 drive chain is designed for competition use and OEM replacement applications. This 150-link chain is engineered to provide dependable power transfer, durability, and reduced friction for compatible motorcycles and powersports vehicles using a 525 chain size. The chain’s Quadra X-Ring design helps retain lubrication more effectively than conventional O-ring chains, supporting extended service life in demanding riding conditions.
Lightening holes help reduce rotating weight, while the optimized seal design minimizes friction and helps protect internal components from contamination. Compared with a standard O-ring chain, the EK 525 SRX2 can provide chain life approximately 1.5 to 2 times longer when properly installed, lubricated, and maintained. It is suitable for high-performance applications where consistent operation and long-term durability are important.
This EK chain includes a screw-type master link for installation and service convenience. Verify motorcycle fitment, chain size, required link count, and master-link compatibility before installation. Manufacturer: EK Chain. Brand: EK. Manufacturer part number: 525SRX2-150.
