Manufacturer Ref: 420SH-STL 78 SPJ — Transmission chain EK CHAIN 420SH 420, designed to equip lightweight cross, quad, and roadster machines where reliability and longevity are sought.
This 420SH chain is aimed at urban riders as well as amateur competitors: not 420, 78 links, and steel/steel construction for mechanical performance suited to the traction and abrasion stresses encountered in off-road conditions. Its design emphasizes the wear resistance of the links and rollers to ensure a smooth power transmission between the sprocket and the crown.
Ideal for small displacement cross and motocross bikes (e.g., HONDA CRF 150 R, YAMAHA YZ 85 LW, KTM 65 SX), this chain installs easily with a suitable tensioner and regular maintenance (cleaning and lubrication) to limit premature wear. It is also suitable for quads and roadsters requiring a robust and easy-to-implement chain.
