EK 520SRX2 QX-Ring Chain 520 (Manufacturer's ref: 520SRX2-GLD/GLD 122) — a transmission chain designed for demanding riders looking for a robust and aesthetic part. The SRX series is known for its recognized quality/price ratio and continuous evolution of manufacturing processes.
This 520SRX2 is offered in a gold finish (Gold/Gold) and features 122 links, suitable for installations requiring this number of links or to be cut according to manufacturer recommendations. It adopts QX‑Ring seals, designed to limit lubricant loss at the rollers and help reduce wear compared to an unsealed chain.
Versatile, it adapts to many environments: quad, urban, motocross, roadster, trail/adventure, vintage, touring, sports/racing, enduro, trial, and supermoto. Particularly suitable for models mentioned in top usage like KTM 690 SMC R, YAMAHA YZ 450 F, or HONDA CRF 300 L (check the number of links and compatibility with your sprocket/crown before installation).
An essential spare part for maintaining the transmission: install it with correct fastening, appropriate tension, and proper lubrication to ensure smooth riding.
