The EK CHAIN 520M3 14/51 chain kit is designed for the motocross rider seeking a lightweight and high-performance transmission without compromising grip. This gold/gold version combines a robust 520 chain with an ultra-light aluminum sprocket, tailored to meet the demands of muddy terrains, jumps, and fast sections encountered in competition or intensive training.
The EK/PBR 520M3 chain minimizes friction while providing good resistance to tension and abrasion, suitable for the demands of motocross. To maintain longevity and operational precision, regular maintenance (cleaning, lubrication, and tension checking) is recommended after muddy outings or when the transmission is heavily stressed.
Frequent compatibilities: KTM 250 SX-F (2022, 2021), HUSQVARNA FC 250 (2021) — check the number of teeth and pitch on your bike before installation. Manufacturer reference: Not provided.
