EK/PBR 520M3 Chain Kit 14/50 - ultra-light sprocket: a set designed for motocross practices where the weight/strength ratio matters. The 520M3 chain by EK CHAIN combines a golden finish and reinforced design to limit friction while providing good resistance to tension and abrasion. The ultra-light aluminum sprocket reduces unsprung mass for a livelier handling of the bike.
Designed to equip motocross machines, this kit is aimed at riders looking for a reliable and lightweight chain for intensive track use. Compatible with models like the KTM 350 XC‑F (2012, 350 cm³), it allows for a more responsive acceleration due to the reduction of unsprung mass. Be sure to follow the installation torque and regular maintenance (tension, lubrication) to maximize the longevity of the final drive.
