An e-moto's instant torque chews through a weak chain fast, which is why this is built around the EK 420SH — a non O-ring chain that keeps power loss to a minimum instead of dragging on O-ring seals. It's cut and sized based on your sprocket setup, so whether you're running stock gearing or something custom, there's a length that matches. Riders who've regeared for more top speed or more low-end torque both end up here, since the right chain length depends entirely on your final sprocket choice. Compatible With: Sur-Ron Light Bee Talaria other 420-chain e-motos Features: EK 420SH chain — a proven, high-strength chain platform Non O-ring / standard construction for minimal power loss versus O-ring chains Gold inner and gold outer plates for a clean, finished look Black carbon rollers for smooth, durable engagement C-clip master link for straightforward install and removal Available in link counts matched to sprocket size — 104 links for 42T up to 116 links for 64T, with 106 links as the OEM 48T size Match the link count to your sprocket size using the sizing chart before you order, so you're not stuck re-cutting or buying a second chain. Ships fast from the USA, straight to your door. Frequently Asked Questions How do I know what chain length I need?Match it to your sprocket tooth count: 42T needs 104 links, the OEM 48T size needs 106 links, 52T needs 108, 54T needs 110, 56T and 58T need 112, 60T needs 114, and 64T needs 116 links.Why is this a non O-ring chain instead of O-ring?O-ring chains hold grease better but create extra drag from the seals rubbing against the plates. This standard 420SH chain skips that drag for minimal power loss, which matters more on an e-moto's instant-torque powertrain.Does this fit bikes other than Sur-Ron?Yes — it's built on the widely-used 420 chain standard, so it fits Sur-Ron Light Bee, Talaria, and other e-motos running 420 chain and sprockets, as long as you match the link count to your gearing.
