Features

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

Designed for the demands of motocross, this chain kit combines a 520 MRD7 chain and an ultra-light aluminum sprocket. Gold/gold finish for a racing look and protection against corrosion. Ideal for riders seeking a lightweight, precise, and reliable drive system for off-road outings.

Type: Complete kit (chain + sprocket + ultra-light sprocket)
Pitch: 520
Number of links: 114
Sprocket/Crown sizes: 13/50
Color: Gold / Gold
Sprocket material: Aluminum (ultra-light)
Weight: 1.47 kg / 100 links
Relative lifespan: 450 (for 100 links)

The MRD7 chain features a design aimed at reducing friction losses while maintaining good abrasion and tensile strength—qualities appreciated in rough terrain. The ultra-light aluminum sprocket helps reduce the unsprung weight of the rolling chassis, enhancing maneuverability during corner exits and direction changes.

Common compatibility: YAMAHA YZ 250 F (2018‑2021), YZ 250 FX. Check the number of links and the sprocket/crown size before installation for a perfect fit.
