The EK 525 SRX2 drive chain is designed for motorcycle competition use and OEM replacement applications. This gold-finished chain includes 150 links and is engineered to provide dependable power transmission, smooth operation, and extended service life for compatible 525-size chain drive systems. The EK 525SRX2 model is supplied with a screw-type master link for convenient installation when properly matched to the motorcycle’s fitment requirements.
Lightening holes help reduce rotating weight, while the reduced-friction construction supports efficient drivetrain performance. EK’s Quadra X-Ring design helps retain lubricant and limit contamination, extending chain life approximately 1.5 to 2 times longer than a standard O-ring chain under comparable operating conditions. The combination of durable construction and low-friction performance makes this chain suitable for demanding street, racing, and replacement applications.
Before installation, verify that the 525 chain size, 150-link length, gold finish, and master-link style match the motorcycle manufacturer’s specifications and the existing sprocket setup. The manufacturer part number is 525SRX2-150G, and the vendor part number is 525SRX2-150G. Proper alignment, lubrication, tension adjustment, and regular inspection are recommended to support long-term performance.
