Product Overview
This high-quality Original Gasket Cylinder is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2012-2020) models.
The Gasket Cylinder sits between the cylinder barrel and the crankcase, forming an oil-tight seal at the base of the cylinder and isolating the oil drain and return passages that cross the joint. When the gasket deteriorates, compresses unevenly, or is disturbed during servicing without replacement, oil seeps past the seal, leading to external base leaks, reduced oil levels, and contamination of surrounding engine components. This original replacement is manufactured to original factory specifications, restoring reliable performance to your Honda scooter.

Complete Part Guide
The cylinder base gasket (12191-KZR-600) is the critical pressure seal for Honda PCX125 models (2012-2020), ensuring a leak-free join between the cylinder block and the crankcase. If this gasket perishes, you will notice oil weeping from the lower cylinder area, leading to low oil levels and potential engine overheating. This original Honda gasket provides the precise thickness required to maintain factory compression and cooling performance. Held at Part Hive's London warehouse; order before 1 PM for same-day UK dispatch.
Oil weeping from the lower engine cases is a frequent sight on 2012-2020 Honda PCX-125 units, often indicating that the 12191-KZR-600 gasket is damaged or was improperly seated during a previous repair. When we perform top-end teardowns, we often find that using liquid sealant in place of a proper gasket is a major error that can lead to blocked oil galleries and terminal engine damage. It is essential to use a fresh base gasket whenever the cylinder is lifted to maintain the correct squish clearance. This original Honda Gasket ensures a factory-spec fit that won't have you back on the bench within a month, replacing leaking, overheated, or crushed gaskets.
