EK CHAIN 520SRX2 QX-Ring 520 (manufacturer reference: 520SRX2-STL 86 SKJ) — transmission chain designed to offer a relevant compromise between cost and reliability. The SRX series is favored by riders for its consistency and regular improvements; this QX-Ring variant maintains the reputation of the range while preserving the sealing of the friction points.
The QX-Ring sealing system helps to limit lubricant loss and protects the pins against contaminants, making maintenance easier and extending peace of mind on the road as well as off-road. Designed for transmissions equipped with a 520 pitch, this chain adapts to urban, road, off-road, and more demanding uses.
Ideal for riders with machines like the KTM 690 SMC R, YAMAHA YZ 450 F, or HONDA CRF 300 L (check compatibility according to sprocket/crown), the 520SRX2 from EK is a serious option for those seeking a robust, easy-to-maintain, and versatile chain.
