EK/PBR 520SRX2 Chain Kit 13/48 - Ultra-Light Sprocket
Designed for off-road enthusiasts, this EK SRX2 chain kit combines the strength of a 520 chain with an ultra-light aluminum sprocket. Ideal for motocross machines where every gram counts, it embodies the SRX philosophy: a balance between performance and value, with regular improvements to remain reliable on the trails.
This kit is aimed at riders who want a complete transmission ready to install, with a lightweight sprocket to minimize rotating mass. As always, regular maintenance (cleaning, lubrication, and proper tension) is essential to get the best performance from the chain and extend its lifespan.
