EK 420SH 420 Transmission Chain – Manufacturer Ref: 420SH-STL 122 SPJ
The EK CHAIN is designed for the transmission of small displacement engines and off-road machines. Suitable for urban, quad, motocross, and roadster environments, it is aimed at riders looking for a robust replacement part that adheres to the 420 pitch.
Designed to limit friction and resist common abrasion in off-road use, this chain uses a standard 420 design compatible with the sprockets and tensioners of small motocross bikes and quads. Its steel/steel treatment gives it a sleek finish and good mechanical resistance for everyday use and amateur competition.
Compatible with numerous models, it is particularly suitable for the HONDA CRF 150 R (2026), YAMAHA YZ 85 LW BIG WHEELS 19/16 (CB10) (2026), and KTM 65 SX (2025). Ideal for transmission restoration, it installs as a direct replacement for configurations requiring 122 links at a 420 pitch.
