EK Chain 420SH – Racing Motocross Chain

The EK Chain 420SH is a racing chain specifically developed for motocross and off-road applications. It is designed to combine low friction, high strength and reliable wear resistance under demanding racing conditions.

High performance with low weight: The 420SH combines a tensile strength of 23.1 kN with a low weight of just 0.91 kg per 100 links. This makes it an ideal choice for lightweight off-road and motocross motorcycles up to 150 cc.

Developed for Motocross and Off-Road

EK Chain's SH series is specifically designed for motocross and off-road racing. Its non-sealed construction helps reduce friction losses and supports direct power transmission.

High wear resistance

The chain pins are designed to provide improved wear resistance. This allows the 420SH to deliver reliable performance even under high loads and repeated shock loads.
