Crafted with precision and designed for high performance, this kit is engineered to meet or exceed original equipment (OE) standards.\n\nAthena, a leader in motorcycle spare parts for over 40 years, utilizes advanced CNC machining tools to ensure exceptional dimensional tolerances of less than 0.01 mm. The pistons are constructed from a specialized high-performance aluminum alloy with a high silicon content, offering superior resistance and excellent performance compared to standard pistons.\n\nThe smooth piston profile promotes optimal airflow and efficient flame propagation. Some piston skirts feature a molybdenum disulfide coating applied via screen printing, further reducing friction to boost performance and durability. Each piston is meticulously engineered in Italy by Athena's R&D department and undergoes rigorous testing on engine dynamometer benches and on the track to validate its performance under extreme conditions.\n\nThis piston kit is specifically designed for use with Athena Big Bore cylinder kits and includes piston rings that minimize friction with the cylinder, leading to higher performance. The piston rings are produced in Japan with wear-resistant coatings, such as PVD or chromium nitride, to increase lifespan and durability. These rings are designed to adapt perfectly to the cylinder liner, even under low tangential load.\n\nThis kit contains all necessary components for installation:\n\n \n- Piston\n \n- Piston Pin\n \n- Circlips\n \n- Piston Rings\n\nAll components are replaceable and interchangeable for convenient servicing.\n\n#### Technical Specifications:\n\n \n- Piston Type: Forged\n \n- Bore Diameter: 96.94 mm\n \n- Big End Pin Diameter: 21x13.5x51 mm\n \n- Compression Height: 26.00 mm\n \n- Piston Pin Type: Biconical\n \n- Number Of Segments (Rings): 3\n \n- Compression Ratio: STD\n \n- Displacement: 450 cc\n \n- Net Weight: 0.44 Kg\n\n**Note:** Products designed for displacements and power exceeding road code regulations are intended exclusively for competitive use.
