The EK/JT 520M3 chain is suitable for the constraints of motocross: grip, repeated RPM changes, and abrasive projections. The ultra-light aluminum sprocket reduces unsprung mass for better throttle response, while the kit assembly (sprocket + rear sprocket + chain) ensures a coherent transmission that is ready for installation. Gold color for an aesthetic finish on the frame and swingarm.
Notable compatibility: YAMAHA YZ 250 (1991‑1993). Check the desired number of teeth and compatibility with the swingarm before installation.
