Features

EK/PBR 520MRD7 Chain Kit 14/48 - Ultra-Light Sprocket

Designed for demanding motocross riders, this EK CHAIN kit combines a robust 520MRD7 chain with an ultra-light aluminum sprocket. Ideal for competitive environments, it minimizes friction while maintaining high resistance to tension and abrasion — essential qualities on rugged and muddy terrain.

Type: 520 Chain Kit (sprocket/crown 14/48)
Number of Links: 112
Color: Gold / Gold (chain and plate)
Sprocket Material: Ultra-light Aluminum
Pitch: 520
Weight: 1.47 kg / 100 links
Relative Lifespan: 450 (for 100 links)

The provided chain-sprocket combination allows for a complete and harmonious replacement of the transmission, minimizing play and facilitating the tuning of the motorcycle. The aluminum sprocket reduces unsprung mass, making it practical for those seeking a lightweight feel at the rear without compromising mechanical stability.
