Product details :

Features

EK/JT 520MRD7 13/49 Chain Kit - ultra-light sprocket, signed by EK CHAIN, designed for motocross riders who want a lightweight and reliable drive system. This kit combines a 520 gold-on-gold chain with an ultra-light aluminum rear sprocket, ideal for reducing unsprung mass without complicating maintenance.

Type: 520 chain kit (sprocket 13 / sprocket 49)
Number of links: 114
Color: Gold / Gold
Sprocket material: Aluminum (ultra-light)
Weight: 1.47 kg / 100 links
Relative lifespan: index 450 (for 100 links)

Designed for motocross and off-road configurations, this kit prioritizes lightweight and abrasion resistance to meet the demands of challenging terrains. The gold finish facilitates visual identification during inspections, and the steel drive sprocket pairs well with the aluminum sprocket to limit weight without sacrificing mechanical integrity.
