Product Overview
This high-quality Original Gasket Cylinder is designed to meet or exceed factory performance standards and is suitable for Honda PCX125 (2021-2025) models.
The gasket cylinder is a precision sealing component positioned between the cylinder barrel and its mating surfaces, forming a gas-tight and oil-tight barrier that maintains correct compression pressure and prevents fluid leaks within the engine's cylinder assembly. As the gasket ages or is subjected to engine overheating, the material can compress permanently, crack, or blow, resulting in compression loss, oil contamination, or external sealing failures that affect engine performance and reliability. This original replacement restores the original cylinder sealing integrity, ensuring seamless, secure, and reliable operation of your PCX125.

Complete Part Guide
The cylinder base gasket on your Honda PCX125 2021-2025 acts as the critical barrier keeping engine oil inside the crankcase and contaminants out. If this seal is compromised, you will notice oil seeping from the bottom of the cylinder, which can lead to low oil levels and eventual engine seizure. This original Honda gasket (12191-K1Z-J11) is made from specialized composite materials to handle the extreme heat of the 2021-2025 liquid-cooled engine. Held in stock at Part Hive’s London warehouse, order before 1 PM for guaranteed same-day UK dispatch.
A leaking base gasket is something we frequently see on PCX units that have been overheated or where low-quality aftermarket gaskets were used during a previous top-end refresh. The 2021-2025 Honda PCX-125 relies on this exact 12191-K1Z-J11 gasket thickness to maintain factory compression ratios; risky fixes using liquid sealant alone will inevitably fail and could block vital oil galleries. We always recommend replacing the base gasket whenever the barrel is lifted to ensure a perfect, high-pressure seal. This original Honda Gasket guarantees a factory-spec fit that won't have you back on the bench within a month, replacing leaking, overheated, or crushed aftermarket gaskets.
