The EK/JT 520M3 14/50 chain kit - ultra-light sprocket combines a high-performance 520 chain and an optimized sprocket/crown setup for motocross use. Designed to minimize friction while supporting the demands of off-road use, this kit prioritizes lightness and responsiveness thanks to its ultra-light aluminum crown and golden finish that facilitates visual maintenance.
Suitable for the demands of the terrain and the tight transmission settings of motocross, this kit pairs particularly well with 350 cc models in the cross category (e.g., KTM 350 SX-F, Husqvarna FC 350). Ideal for riders looking to reduce unsprung mass while maintaining a strong chain and a polished look. Check the number of links and the spacing before installation for a perfect fit to your machine.
