Features

EK/JT 520M3 Chain Kit 12/48 - Ultra-Light Sprocket

Designed for motocross riders seeking a reliable and lightweight kit, this 520M3 combines a gold EK chain with an ultra-light aluminum sprocket in gold finish. Ideal for motocross use, it reduces unsprung mass while providing smooth transmission and precise drive on muddy or rough terrain. The kit is suitable for setups aiming to optimize acceleration and maneuverability without sacrificing wear resistance.

Configuration: 12-tooth sprocket / 48-tooth sprocket (complete kit)
Chain Type: 520, 112 links
Color: Gold / Gold
Sprocket Material: Ultra-light aluminum
Relative Lifespan: 450 (for 100 links)
Weight: 1.36 kg for 100 links

Easy to install for equipped mechanics, this kit is designed to withstand the pulls and friction inherent to motocross while minimizing rear wheel inertia. Compatibility confirmed with several KAWASAKI KX125 models (1998–2002). Check the number of links and the original sprocket before installation for precise tension adjustment.
