EK/PBR 520MRD7 Chain Kit 14/48 - Ultra-Light Sprocket
Specifically developed for motocross, this EK/PBR chain kit combines a high-performance 520 chain and an ultra-light aluminum sprocket. Designed for the demanding conditions of motocross tracks, it aims to minimize friction while maintaining durability against the traction and abrasion encountered in competition and intensive training.
The kit is aimed at motocross riders seeking a lightweight and responsive transmission: reduced unsprung mass, choice of ratios suited to the terrain, and a gold finish for a racing look. Compatible with many 250cc off-road bikes — notably HUSQVARNA WR 250 (1999 and 2000) — it is suitable for a restoration or a transition to competition setup. Be sure to check the exact compatibility with your model and regularly monitor tension and lubrication to optimize the longevity of the transmission.
