Focused on reliability, it is aimed at motocross machines where robustness and longevity of the transmission are essential. The EK 420SH is a standard sealed chain without O-Ring technology, treated with CRH-Pin technology: hardened outer layer to resist wear, softened core for better shock resistance.

The tooth profile and machining precision of the PBR parts ensure a snug fit with the 420 chain, minimizing jolts and premature wear.
