This kit is aimed at motocross riders looking for a 520 pitch chain with a lightweight aluminum crown treated to withstand the stresses of the terrain. The "ultra-light" crown reduces unsprung inertia, while the anodized finish provides protection against abrasion and debris. The standard 520 pitch and the number of links make it compatible with many typical off-road suspensions and geometries.
Common compatibilities: HUSQVARNA TC 450 (2005, 2007, 2010) — always check the length and position of the sprocket on your machine before installation. Regular maintenance and tension adjustment are recommended to optimize longevity and safety.
