Features

EK/JT 520MRD7 15/48 Chain Kit - Ultra-Light Sprocket

Designed for off-road and motocross competition, this EK CHAIN kit combines a robust 520 chain with an ultra-light aluminum sprocket. Ready to install in a 15/48 configuration, it is aimed at riders seeking reliability, lightweight performance, and a refined finish for their secondary transmission.

Configuration: 15-tooth sprocket / 48-tooth sprocket / 114 links (complete kit)
Pitch: 520, suitable for mid-displacement motocross and enduro bikes
Sprocket Material: ultra-light aluminum — reducing unsprung weight
Finish: chain and sprocket in gold color
Durability: relative lifespan index of 450 (for 100 links)
Weight: 1.47 kg for 100 links (indicative value)

Easy installation to prepare your machine for intensive sessions — both training and championship heats. The combination of EK chain and aluminum sprocket minimizes friction while being designed to withstand the demands of the terrain.
