The TVS ROCKZ 125 motorcycle is equipped with a primary clutch assembly, which is an important component of the motorcycle's transmission system. However, I don't have access to specific information about the primary clutch assembly model for the TVS ROCKZ 125. Here is some general information about motorcycle primary clutch assemblies:

Function: The primary clutch assembly is responsible for transmitting power from the engine to the transmission. It engages and disengages the engine's power to the transmission, allowing for smooth gear shifting and control of the motorcycle's speed.

Design: A motorcycle's primary clutch assembly typically consists of several components, including a clutch basket, clutch plates, pressure plate, and a clutch hub. When the clutch lever is engaged, the clutch plates are pressed together, connecting the engine's power to the transmission. When the clutch lever is disengaged, the clutch plates separate, allowing the rider to shift gears or come to a stop without stalling the engine.

Operation: The primary clutch assembly operates based on friction and pressure. The clutch plates, usually made of steel and friction material, create friction when pressed together, transferring power from the engine to the transmission. The pressure plate exerts pressure on the clutch plates, allowing them to engage or disengage smoothly.

Maintenance: Proper maintenance of the primary clutch assembly is crucial for optimal performance. This includes regular inspection for wear or damage, ensuring proper lubrication, and adjusting the clutch cable or hydraulic system if necessary. If the primary clutch assembly is worn out or damaged, it may need to be replaced to maintain proper clutch engagement and operation.

For specific details about the primary clutch assembly model used in the TVS ROCKZ 125 motorcycle, I recommend referring to the official TVS documentation, contacting authorized TVS dealers or service centers, or reaching out to TVS customer support for accurate and up-to-date information.
