CG 125 Motorcycle 4 Valve Engine Cylinder 125cc Air-cooled Engine Parts for Replacement
The motorcycle cylinder sleeve refers to a component installed inside the engine cylinder block, typically used to repair or replace heavily worn engine cylinders. Its primary function is to provide a new inner diameter surface that works with the piston, restoring the engine's sealing and performance. Cylinder sleeves are usually made of durable materials such as cast iron or aluminum alloy, known for their high wear resistance and heat conductivity to ensure proper engine operation and long-term reliability.
