EK/PBR 520 SRX2 Chain Kit - 13/52-116 by EK CHAIN: a kit designed for the transmission of motocross machines, focusing on durability and ease of maintenance. The SRX2 series offers a good balance between longevity and cost, appreciated by riders who ride on challenging terrains.
This chain kit is suitable for off-road and motocross use where the transmission undergoes repeated stresses: sharp accelerations, jumps, and restarts. The standard steel crown provides resistance to shocks and contact with stones or branches, while the reinforced SRX2 chain withstands the typical traction forces of trail and cross engines.
Installation: the attachment is to be riveted, so ensure you have the appropriate tool or have it installed in a workshop for secure riveting. Remember to adjust the tension and regularly lubricate the chain to preserve the lifespan of the whole assembly. Compatibility examples: motocross bikes such as the GAS GAS EC 350 F (2024 - 350 cc) — always check the sprocket/crown ratio recommended by the manufacturer.
