EK/PBR 520SRX2 Chain Kit 13/50 - Ultra-Light Sprocket
Designed for motocross riders seeking a robust and reliable chain without compromising on cost, this EK SRX kit combines the longevity of a 520 chain with an ultra-light aluminum sprocket to reduce unsprung mass. Ideal for maintenance replacements or restoration after intensive use.
The EK SRX series is valued for its good performance-to-price ratio and regular updates. This kit is particularly suitable for off-road motorcycles equipped with 520, providing a complete solution — sprocket, chain, and sprocket — to quickly restore the transmission to working order.
Common compatibilities: KTM 125 XC-W (2017, 2018, 2019). Before purchasing, check the number of teeth and pitch on your machine to ensure proper fit. Regular installation and maintenance are recommended to preserve the lifespan of the chain and sprocket.
