EK/PBR 520MVXZ2 Chain Kit 15/42 - Ultra-light Hard Anodized Sprocket
Designed for demanding riders, this EK MVXZ chain kit combines a QX sealed chain and an ultra-light hard anodized aluminum sprocket. Its design emphasizes durability and friction reduction: side plates are drilled to lighten without compromising rigidity, large diameter pins for better stress distribution, and QX seals aimed at limiting friction between links.
This kit is aimed at road bikes and roadsters seeking a balance between lightness, longevity, and transmission reliability. Ideal for owners of listed models (e.g., KTM RC 390 ABS 2022–2024), it serves as a robust replacement option to restore the transmission to working order. Regular installation and maintenance are recommended to take full advantage of the chain and sprocket's performance.
