Product details :

Features

EK CHAIN EK/JT 520MRD7 13/51 Chain Kit - ultra-light sprocket: a transmission set designed for motocross riders who want a lightweight and robust solution. The 520MRD7 chain, in gold/gold finish, combines a durable construction with an ultra-light aluminum rear sprocket to minimize unsprung mass without sacrificing track performance.

Type: 520 chain kit (fits 520) with 13-tooth sprocket / 51-tooth sprocket
Number of links: 116 links
Color: Gold / Gold
Weight: 1.47 kg for 100 links (reference)
Sprocket material: Ultra-light aluminum
Durability index: 450 (relative value for 100 links)

Designed for the demands of motocross, this chain withstands sharp accelerations, jumps, and abrasive stresses encountered in competition. The aluminum sprocket reduces rotating weight for a more responsive transmission, while the gold finish aids in visual inspection and limits corrosion during intensive use.

Common compatibilities: YAMAHA YZ 125 (1990–1992). Always check the spacing and adjustment on your machine before installation.
