Product details :

Features

EK/JT 520M3 Chain Kit 14/51 - Ultra-Light Sprocket
Brand: EK CHAIN — Cross Special. Complete chain kit with 14-tooth sprocket / 51-tooth rear sprocket, designed for the final drive of off-road motorcycles. Engineered to withstand the demands of the terrain and intensive competition use, this kit combines lightness and robustness.

Pitch type: 520 (520M3)
Number of links: 116 (to be shortened if necessary)
Color: Gold / Gold
Sprocket: Aluminum, ultra-light version
Weight: 1.36 kg for 100 links
Relative lifespan: 450 (for 100 links, manufacturer value)
Manufacturer reference: Not provided

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.
