Supplied as a full rebuild package, the kit includes the machined aluminum cylinder, matching piston and rings, wrist pin and clips, gaskets, stud hardware, and seals so you can swap parts without sourcing additional components.\u003c\/p\u003e\n\n\u003ch3\u003eHow does this kit increase engine performance?\u003c\/h3\u003e\n\n\u003cp\u003eBy raising the bore to 47mm and supplying a compatible high-compression piston, the kit increases total cylinder volume to roughly 80cc. The larger displacement allows the engine to ingest and burn a greater fuel\/air charge per cycle, producing stronger low- and mid-range torque for quicker acceleration off the line.\u003c\/p\u003e\n\n\u003cul\u003e\n  \u003cli\u003e47mm inner cylinder diameter for 80cc displacement\u003c\/li\u003e\n  \u003cli\u003ePrecision-machined piston and rings for improved sealing\u003c\/li\u003e\n  \u003cli\u003eIncludes gaskets and studs to maintain proper compression\u003c\/li\u003e\n  \u003cli\u003eDesigned for GY6 49–60cc platform compatibility\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat components are included, and why does that matter?\u003c\/h3\u003e\n\n\u003cp\u003eThe Glixal kit ships as a complete rebuild bundle so you avoid compatibility mismatches and extra sourcing.
