Left Rear Crankcase Cover

The Left Rear Crankcase Cover is a protective engine housing located on the rear section of the left side of the motorcycle’s crankcase. It is designed to seal, protect, and support several internal components related to the engine’s lubrication, transmission, or electrical systems—depending on the motorcycle model.

Main Functions

• Protects internal engine components, such as transmission elements, oil passages, or secondary mechanisms located at the rear-left of the crankcase.

• Provides a sealed enclosure to prevent oil leakage and keep dust, dirt, and moisture from entering the engine.

• Serves as a structural support for certain components like the gearshift mechanism or rear crankshaft bearings.

• Helps maintain proper engine lubrication by enclosing oil channels and internal moving parts.
