EK/PBR 520MRD7 13/48 Chain Kit - Ultra-Light Sprocket
Designed for motocross and the demanding environments of competition, this EK CHAIN kit combines a high-performance 520 chain with an ultra-light aluminum sprocket. The gold finish provides a racing look while the design aims to minimize friction while offering good resistance to traction and abrasion on muddy or dusty terrains.
This kit is aimed at motocross riders looking for an optimized drive system, featuring a lightweight sprocket to reduce unsprung mass and a chain designed to withstand the typical demands of off-road riding. Compatible with many vintage and modern 250 cc machines — cited example: KTM 250 GS (1992) — it remains important to check the installation, tension, and maintenance (regular lubrication) to get the best performance from the set.
