EK/PBR 520 M3 Chain Kit - 13/49-116 by EK CHAIN: a set designed for Cross motorcycles that includes a reinforced chain, sprocket, and standard steel rear sprocket. Ideal for demanding riders who want a robust and easy-to-maintain transmission in muddy or abrasive terrain.
EK's M3 design prioritises tensile strength and abrasion resistance, essential elements in rocky or muddy areas. The steel sprocket provides good longevity, while the semi-pressed link makes replacement easier at the trackside. This kit is suitable for common motocross transmissions; however, please check the installation and tension adjustment on your machine before use.
Examples of compatible models (for reference): KTM 300 SX (2026), GAS GAS EX 300 (2026), HUSQVARNA TX 300 I (2024). For optimal performance, remember to regularly check the alignment, tension, and lubrication of the chain.
