This kit provides improved resistance and excellent performance.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThe Athena Piston Kit is designed for enthusiasts and professionals seeking to maximize their engine's potential. Crafted from a high-performance aluminum alloy with a high silicon content, this piston ensures reliability comparable to OE pistons while offering enhanced strength. The smooth piston profile optimizes gas flow and flame propagation, contributing to a more efficient combustion process. Manufactured using reverse extrusion and CNC machining, this piston delivers unparalleled precision. The piston rings, made in Japan, minimize friction with the cylinder wall, increasing overall performance. The 77.96 mm bore size and 13.5:1 compression ratio are perfectly matched for optimal engine output. Experience the difference with Athena – where quality meets performance.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003eHigh-performance aluminum alloy construction for superior strength and heat resistance.\u003c\/li\u003e\n \u003cli\u003eSmooth piston profile ensures regular flow and optimal flame propagation.\u003c\/li\u003e\n \u003cli\u003eCNC-machined for precise dimensions and exacting tolerances.\u003c\/li\u003e\n \u003cli\u003ePiston rings made in Japan with wear-resistant coatings (PVD or chromium nitride) for extended life.\u003c\/li\u003e\n \u003cli\u003eOptimized for 250cc 4-stroke off-road motorcycles.\u003c\/li\u003e\n \u003cli\u003eImproved design reduces friction for maximum power output.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical specifications\u003c\/h2\u003e\n\u003cul\u003e\n \u003cli\u003eBrand: Athena\u003c\/li\u003e\n \u003cli\u003ePart Number: 09031739\u003c\/li\u003e\n \u003cli\u003eBore Size: 77.96 mm\u003c\/li\u003e\n \u003cli\u003eCompression Ratio: 13.5:1\u003c\/li\u003e\n \u003cli\u003eDisplacement: 250 cc\u003c\/li\u003e\n \u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n \u003cli\u003ePiston Material: Forged Aluminum Alloy\u003c\/li\u003e\n \u003cli\u003eType: Top End\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eImportant to know\u003c\/h2\u003e\n\u003cp\u003eThis kit includes the necessary components for a top-end piston replacement.
