EK/PBR 520M3 Chain Kit 13/50 - Ultra-Light Sprocket: a chain kit designed for motocross, combining a robust chain and a lightweight aluminum sprocket.

Designed to withstand the demands of the terrain (traction, abrasion), this chain + sprocket combination is aimed at motocross riders who want a lightweight feel and a golden aesthetic. Compatible with trail/enduro bikes in the 250 cross category — notably including the KTM 250 SX-F (2014-2016) — it installs on setups designed for the 520 pitch and the 13/50 configuration. For optimal longevity, check the alignment, tension, and regular maintenance of the chain after each ride.
