Product details :

Features

The EK/JT 520MRD7 13/50 chain kit combines a high-performance chain with an ultra-light aluminum sprocket for motocross use. Designed to withstand the demanding environments of competition, this kit minimizes friction while providing good traction and abrasion resistance—qualities sought after by off-road riders concerned with reliability and handling.

Type: 520 chain kit with 13-tooth sprocket / 50-tooth sprocket (ultra-light)
Color: Gold / Gold — racing look and visual anti-corrosion
Number of links: 114 links (ready to be adjusted according to installation)
Pitch: 520
Weight: 1.47 kg for 100 links (light for the category)
Sprocket material: Aluminum — significant mass reduction for inertia
Wear index (100 links): 450 (relative value provided)
Brand: EK CHAIN — a renowned specialist in motorcycle transmission

Ideal for cross riders who want a lightweight and robust drivetrain, this kit fits many enduro/cross bikes including the Kawasaki KLX 450 R (2017 to 2019 models). Regular adjustment and maintenance (tension, lubrication) are recommended to make the most of its characteristics both on the track and during training days.
