EK/PBR 520MRD7 Chain Kit 14/52 - Ultra-light Anodized Sprocket
Specifically designed for motocross, this EK CHAIN kit includes a 520MRD7 chain and a 14/52 sprocket/crown combination. Built for the demanding conditions of off-road riding, it features a gold chain and an ultra-light hard anodized aluminum sprocket to minimize unsprung mass without compromising abrasion resistance.

The assembly reduces rotational mass and mechanical drag, advantageous on rough terrain and during acceleration phases. Ideal for motocross riders and gear shifts on machines like HUSQVARNA TC 610 (years 1998-2000). To maintain performance, regularly check the tension, clean and lubricate the chain after muddy rides, and replace worn components in stages to preserve the transmission.
