The motorcycle center clutch assembly, also known as the clutch center or clutch hub assembly, is a critical component of a motorcycle's clutch system. It is responsible for transmitting power from the engine to the transmission by engaging and disengaging the clutch.

The center clutch assembly is typically located in the center of the clutch system, between the engine and the transmission. It consists of several key components, including:

Clutch Hub: The clutch hub is a cylindrical component that connects directly to the engine's crankshaft. It rotates with the engine and transfers the engine's power to the clutch assembly.

Clutch Plates: The clutch plates are a set of alternating friction plates and metal plates. When the clutch is engaged, the friction plates are pressed tightly against each other, allowing power to be transmitted from the engine to the transmission. When the clutch is disengaged, the friction plates separate, interrupting the power flow.

Clutch Springs: The clutch springs provide the necessary pressure to keep the clutch plates engaged. They ensure that the friction plates maintain sufficient contact with each other to transmit power effectively. The springs also allow for some slippage to occur between the plates during clutch engagement, providing a smooth engagement and preventing sudden jerks.

Clutch Center Bearing: The clutch center assembly may also include a bearing that facilitates smooth rotation of the clutch hub. This bearing reduces friction and allows the clutch hub to spin freely.
