This high-quality piston is crafted using advanced reverse extrusion and cutting-edge CNC machining for precise dimensional accuracy, ensuring a perfect fit and optimal function.\n\nConstructed from a special high-performance aluminum alloy with a high silicon content, this piston offers superior resistance and durability compared to OE components, while maintaining the same level of reliability.\n\nThe piston features a perfectly smooth profile designed for regular flow and ideal flame propagation. Some applications include a molybdenum disulfide coating on the piston skirts, applied through screen printing, to further reduce friction, boost performance, and extend durability.\n\nAthena engineers are dedicated to providing advanced technical solutions and the highest quality standards, often exceeding OE specifications. Each piston is meticulously engineered in Italy by the Athena R&D department and rigorously tested on engine dynamometers and tracks to validate its performance under extreme conditions.\n\nThis piston kit includes the piston, pin, circlips, and piston rings. The piston rings, produced in Japan with wear-resistant coatings (PVD or chromium nitride), are designed to minimize friction with the cylinder, leading to higher performance and increased longevity. They ensure excellent adaptation to the cylinder liner even at low tangential loads.\n\n#### Technical Specifications:\n\n \n- Piston Type: Forged\n \n- Bore Diameter: 77.96 mm\n \n- Big End Pin Diameter: 16x9x38.2 mm\n \n- Compression Height: 19.40 mm\n \n- Compression Ratio: 13.9:1\n \n- Displacement: 250 cc\n \n- Number of Segments: 2\n \n- Piston Pin Type: Biconical\n \n- Net Weight: 0.19 Kg\n\n**Please Note:** Products designed for greater displacement and power than permitted by local road regulations are intended exclusively for competitive use.
