EK/PBR 520MRD7 13/50 Chain Kit — a set designed for motocross riders seeking a lightweight and durable transmission. The 520MRD7 chain, paired with an ultra-light hard anodized aluminum sprocket, offers a combination of weight reduction and resilience against the demands of trails and jumps. Gold/gold finish for a racing look that withstands external aggressions.
Designed to minimize friction while maintaining good tensile strength and abrasion resistance, this chain kit is aimed at both competitive and amateur motocross riders who want a responsive and lightweight transmission. The hard anodized aluminum sprocket helps reduce unsprung weight and facilitates changes in engine speed, while the gold chain maintains a neat aesthetic despite wear from mud and debris.
Common compatibilities: particularly suitable for Husqvarna WRE 125 (2002–2004). Be sure to check the spacing and tension adjustment during installation to ensure optimal longevity.
