Product details :

Features

The EK/PBR 520MRD7 13/51 chain kit is a set designed for motocross riders seeking lightweight performance and durability in demanding terrain. Comprising a 520 chain and an ultra-light aluminum sprocket, it aims to reduce unsprung mass while maintaining a construction suited to off-road conditions.

Brand: EK CHAIN
Designation: EK/PBR 520MRD7 13/51 chain kit - ultra-light sprocket
Pinion/Sprocket configuration: 13/51
Pitch: 520
Number of links: 116
Color: Gold / Gold
Sprocket material: Aluminum (ultra-light)
Relative lifespan (100 links): 450
Stated weight: 1.47 kg for 100 links

Designed to handle jumps, landings, and mud, the EK chain minimizes friction while providing good tensile strength and abrasion resistance. The ultra-light aluminum sprocket helps reduce unsprung mass for a more responsive rear wheel behavior, without compromising compatibility with 520 transmissions. Ideal for motocross bikes, it easily adapts during routine maintenance or transmission replacement.
