Features

Manufacturer Ref: 420SR-STL 120 SPJ — Product: EK 420SR Transmission Chain

The EK 420SR chain is designed for motorcyclists and DIY enthusiasts seeking a robust and reliable part for small displacement bikes and lightweight machines. Engineered to maintain its flexibility even after prolonged use, the SR series benefits from a specialized heat treatment of the plates that enhances durability and wear resistance. Ideal for urban use, quads, motocross, or roadsters, it fits transmissions where torque and cadence demand a compact 420 pitch chain.

Pitch: 420
Number of Links: 120
Color: Steel / Steel
Relative Lifespan (for 100 links): 200
Weight: 0.75 kg / 100 links

Compatible with many small motorcycles and pit bikes — for example, RIEJU MRT 50 SM (2025), FANTIC XM 50 PERFORMANCE (2025), and BETA RR 50 MOTARD (2025) — this chain installs between the sprocket and the crown to ensure a direct transmission. Adhere to the recommended torque, tension, and proper lubrication to maximize its longevity. A simple and effective choice to restore the transmission and hit the road with confidence.
