EK/PBR 520SRX2 Chain Kit 13/50 - Ultra-light Sprocket
Designed for motocross riders seeking a reliable and lightweight transmission, this EK CHAIN 520SRX2 chain kit combines a 520 chain with an ultra-light aluminum sprocket. The 13/50 setup (13-tooth sprocket / 50-tooth sprocket) is suitable for off-road motorcycles requiring a balance between acceleration and longevity.

The gold finish adds an aesthetic touch to the hubs and swingarm, while the aluminum sprocket reduces unsprung mass for a more responsive behavior on jumps and accelerations. Ideal for motocross/off-road use, this kit fits many enduro and motocross models — notably the KTM 500 EXC-F (2016-2022) listed as compatible references.
Before installation, check the number of links and the alignment of the sprocket. Regular maintenance (cleaning and lubrication) will extend the lifespan of the chain and sprocket, especially in muddy and sandy conditions.
