The EK 420SH E-Moto Chain is a standard, non O-ring drive chain option for Surron and Talaria e-moto setups where low drag and reduced power loss are priorities. This chain uses gold inner and gold outer plates paired with black carbon rollers for a distinctive look and reliable drivetrain function. Supplied in a 120 link length, it gives you extra length to size the chain to your gearing and wheelbase needs. A C clip master link is included to make installation and chain-length changes straightforward during gearing swaps or routine maintenance.
The 420SH is a NON O-ring (standard) chain, specified for less power loss compared with sealed designs. It’s a practical choice for e-moto drivetrains where efficiency and reduced drag are important, while still retaining the familiar service and adjustment approach of a standard chain.
Gold inner and gold outer plates give this chain a clean, high-contrast appearance on Surron and Talaria builds. The look is matched with black carbon rollers, creating a coordinated finish that stands out while still serving the core function of smooth engagement with your sprockets.
Delivered in a 120 link length, this chain can be cut down to suit your final sprocket and wheelbase combination. A C clip master link is included, helping simplify installation and making it easier to remove the chain later for adjustments or drivetrain service.
