Features

Manufacturer's ref: 420SR-STL 144 SPJ

The EK 420SR 420 transmission chain is designed for urban, cross, quad, and roadster use. Coming from the SR series, it features a specific heat treatment of the plates that preserves the chain's flexibility even after long distances, while improving its wear resistance. Ideal for small cylinders and lightweight machines, it fits 420 sprockets and crowns to ensure reliable and smooth transmission.

Brand: EK CHAIN
Designation: EK 420SR 420 transmission chain
Number of links: 144
Pitch: 420
Color: Steel / Steel
Relative lifespan (for 100 links): 200
Weight: 0.75 kg / 100 links

Designed for riders looking for a robust and flexible chain, the EK 420SR is particularly suited for 50 cc machines and other small displacements. Frequent compatibilities include:

RIEJU MRT 50 SM (2025)
