The piston ring set incorporates a steel strip combined oil ring, which is a specific design type for managing engine oil. The ring structure is described as a combination ring, indicating it is not a single piece but an assembly designed to work together for sealing and oil control within the cylinder.\u003c\/p\u003e\n\u003ch3\u003eSize and Practical Fit\u003c\/h3\u003e\n\u003cp\u003ePrecise sizing is crucial for engine parts. This piston kit is intended for engines with a cylinder diameter, or bore, of exactly 57.4mm. The total height of the piston assembly, measuring 37mm from the crown to the bottom of the skirt, is another vital dimension. Matching these measurements to your engine's requirements is essential for proper compression, clearance, and overall engine performance after installation.\u003c\/p\u003e\n\u003ch2\u003eUses and Placement\u003c\/h2\u003e\u003cdiv style=\"text-align: center;\"\u003e\u003cimg alt=\"Motorcycle engine piston kit with rings and pin for 57.4mm cylinder diameter\" src=\"https:\/\/images.seoo.uk\/src\/products\/shopify_export\/US12\/1178\/2025-10-02\/original-image\/74a35453-7225-4b5c-953d-91aec4be0423.webp\"\u003e\u003c\/div\u003e\n\u003cp\u003eThis product serves a specific function within motorcycle maintenance and repair, aimed at restoring engine compression and smooth operation.\u003c\/p\u003e\n\u003ch3\u003eEvent or Professional Use\u003c\/h3\u003e\n\u003cp\u003eFor professional mechanics or experienced DIY enthusiasts performing engine rebuilds or top-end overhauls, this kit provides a ready-to-fit piston assembly. It is suitable for use when the existing piston is damaged, scored, or worn beyond service limits in an engine with the matching 57.4mm bore. Using a complete kit can streamline the parts procurement process for such repairs.\u003c\/p\u003e\n\u003ch3\u003eEveryday Home Use\u003c\/h3\u003e\n\u003cp\u003eFor the home mechanic undertaking a planned engine refurbishment on their motorcycle, having a matched set of piston components can simplify the project.
