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.
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.
