#428 Chain Offset Half Link for Scooters & Mopeds (Standard)

#428 Chain Offset Half Link for Scooters & Mopeds. Chains and sprockets transfer power to the rear wheel on chain-drive scooters, mini bikes and pocket bikes.

Replace them together when the chain stretches or the teeth hook. Match the chain size (for example #25, #35, #41, #420) and tooth count.

Product details

Fine-tune your chain length with the #428 Offset Half Link. Also called a half link, this component lets you adjust chain length by a single pitch instead of the standard two — the perfect solution when your chain adjusters are maxed out or your drive base is fixed. Built from treated high-tensile steel with an ultimate tensile strength of 18.0 kN (4,091 lbs), it's a reliable fit for dirt bikes, ATVs, go-karts, mini-bikes, and pocket bikes running a #428 pitch chain.
