EK/PBR 520MRD7 Chain Kit 13/50 - Ultra-Light Sprocket

Designed for the motocross world, this EK CHAIN kit combines a robust 520 chain with a 13-tooth sprocket and an ultra-light 50-tooth aluminum sprocket. Tailored for demanding riders, it aims to offer a balance between lightweight and strength against the challenges of off-road competition.

• Configuration: 13-tooth sprocket / 50-tooth (ultra-light aluminum sprocket)
• Chain: pitch 520, 116 links
• Color: gold/gold
• Relative durability: index 450 (for 100 links)
• Indicative weight: 1.47 kg for 100 links

This kit is aimed at motocross practitioners who seek a lightweight and responsive transmission without sacrificing traction and abrasion resistance. The aluminum sprocket reduces unsprung weight, contributing to better maneuverability and a quicker response from the output shaft.
