The EK/PBR 520MRD7 14/48 chain kit with ultra-light sprocket is designed for motocross riders who want a reliable transmission without adding weight to the machine. Composed of a gold 520 chain and a lightweight aluminum sprocket, it aims to reduce unsprung mass while maintaining good resistance to tension and abrasion—essential qualities on soft and bumpy terrains.

Compatible with many motocross models—such as the SUZUKI RM-Z 450 (2007)—this kit offers a neat finish and the gold look appreciated for both aesthetic and functional preparations.
