Designed for superior reliability and performance, this kit ensures your off-road motorcycle operates at its peak.\u003c\/p\u003e\n\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eThis Athena piston kit is crafted from a high-performance aluminum alloy with a high silicon content, ensuring reliability comparable to OE pistons while providing enhanced resistance and excellent overall performance. The smooth piston profile optimizes flow and ensures perfect flame propagation, resulting in improved combustion efficiency. Specifically designed for 4-stroke off-road motorcycles, these pistons are manufactured using reverse extrusion and precision CNC machining techniques. The included piston rings minimize friction against the cylinder walls, maximizing performance. These Japanese-made segments feature wear-resistant coatings such as PVD or chromium nitride, increasing retention and overall durability. This kit is optimized for engines with a 78.96 mm bore size and a 14.1:1 compression ratio, suitable for 250cc 4-stroke engines. Upgrade to this top-end piston kit from Athena and experience a noticeable boost in power and dependability.\u003c\/p\u003e\n\n\u003ch2\u003eFeatures \u0026amp; highlights\u003c\/h2\u003e\n\u003cul\u003e\n  \u003cli\u003eHigh-performance aluminum alloy construction ensures superior strength and durability.\u003c\/li\u003e\n  \u003cli\u003eOptimized piston profile promotes smooth flow and perfect flame propagation.\u003c\/li\u003e\n  \u003cli\u003eManufactured using reverse extrusion and CNC machining for precise fit and finish.\u003c\/li\u003e\n  \u003cli\u003ePiston rings designed to minimize friction and maximize performance.\u003c\/li\u003e\n  \u003cli\u003eJapanese-made piston segments with wear-resistant coatings (PVD or chromium nitride) for extended life.\u003c\/li\u003e\n  \u003cli\u003eEngineered for 4-stroke off-road motorcycles to boost power and dependability.\u003c\/li\u003e\n  \u003cli\u003eProvides greater resistance and excellent performance.\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: 09031738\u003c\/li\u003e\n  \u003cli\u003eProduct Name: Piston Kit\u003c\/li\u003e\n  \u003cli\u003eBore Size: 78.96 mm\u003c\/li\u003e\n  \u003cli\u003eCompression Ratio: 14.1:1\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\u003ePlease ensure compatibility with your specific motorcycle model before installation.
