This kit delivers enhanced lubrication, reduced friction, and improved sealing for optimal power and reliability. Built with precision and durability in mind, this piston kit is perfect for enthusiasts and professionals alike.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Wossner Piston Kit features enhanced piston pin oiling slots, radial boss machining, and annular grooves to ensure superior wrist pin lubrication. This reduces friction and wear, extending the life of your engine. The lightweight piston design, combined with a tight piston wall clearance, contributes to a quieter running engine. A skirt coating minimizes friction and aids in break-in, while a ring land treatment enhances ring seal and oil control. Where applicable, a double-bridged forging design adds strength and durability. The piston's forged aluminum alloy construction ensures reliability under demanding conditions, with a 77.96mm piston size designed for a 78.00mm bore and 52.20mm stroke length. The 13.5:1 compression ratio delivers increased power and responsiveness. This kit provides everything you need for a complete piston replacement.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eEnhanced wrist pin lubrication for reduced friction and extended engine life.\u003c\/li\u003e\n  \u003cli\u003eLightweight piston design ensures quieter operation and improved performance.\u003c\/li\u003e\n  \u003cli\u003eSkirt coating minimizes friction and accelerates the break-in process.\u003c\/li\u003e\n  \u003cli\u003eRing land treatment optimizes ring seal and oil control for maximum power.\u003c\/li\u003e\n  \u003cli\u003eForged aluminum alloy construction for superior strength and durability.\u003c\/li\u003e\n  \u003cli\u003eComplete kit includes piston, rings, wrist pin, and pin locks.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eBrand: Wossner\u003c\/li\u003e\n  \u003cli\u003ePart Number: 09104960\u003c\/li\u003e\n  \u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n  \u003cli\u003ePiston Material: Forged Aluminum Alloy\u003c\/li\u003e\n  \u003cli\u003eBore Size: 78.00 mm\u003c\/li\u003e\n  \u003cli\u003ePiston Size: 77.96 mm\u003c\/li\u003e\n  \u003cli\u003eStroke Length: 52.20 mm\u003c\/li\u003e\n  \u003cli\u003eCompression Ratio: 13.5:1\u003c\/li\u003e\n  \u003cli\u003eBore - Oversize: Standard\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003eThis kit includes the piston, rings, wrist pin, and pin locks.
