What is cush drive sprocket?
A cush drive wheel has a separate drive hub that interlocks with rubber dampers between those interlocking fingers. The sprocket is bolted to the outer drive hub or “cush drive”. Those rubber dampers soak up energy that is produced when a shock load occurs from hard acceleration or braking.

Lubrication: After the hub is opened, remove the rubber dampers (Fig. 3) and wipe everything clean. Lubricate the rubber dampers with grease before putting them back again.
What are cush drive rubbers?
They are cush drive rubbers and are designed to absorb the shocks to the system when you come on and off the throttle. It’s unusual for them to be worn this early in the bike’s life, but if the chain has been run very slack that will accelerate the wear. They simply push into position so they are easy to replace.
