Crafted from a special high-performance aluminum alloy with a high silicon content, these pistons offer enhanced reliability, resistance, and excellent performance compared to Original Equipment (OE) pistons. The advanced manufacturing process utilizes cutting-edge CNC machining tools, ensuring dimensional tolerances of less than 0.01 mm. The piston's perfectly smooth profile promotes a regular flow and ideal flame propagation.\n\nSome piston skirts are treated with a molybdenum disulfide coating applied by screen printing. This treatment further reduces friction, enhancing both performance and durability. Athena engineers develop advanced technical solutions and maintain the highest quality standards, meeting or exceeding OE production requirements for optimal performance and reliability.\n\nEach piston is meticulously engineered in Italy by the Athena R&D department. They undergo rigorous testing on engine dynamometer benches under progressive stress loads and are validated on the track in the most extreme conditions to ensure their performance. This piston kit includes the piston, pin, circlips, and piston rings. All components are replaceable and interchangeable.\n\nThe included piston rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) to increase retention and durability. These rings perfectly adapt to the cylinder liner even under low tangential load, ensuring reduced friction with the cylinder for higher performance.\n\n#### Key Features:\n\n \n- Piston Type: Forged\n \n- Bore Diameter: 99.96 mm\n \n- Big End Pin Diameter: 19x9.9x51.1 mm\n \n- Compression Height: 29.00 mm\n \n- Compression Ratio: 12.0:1\n \n- Displacement: 450 cc\n \n- Number Of Segments: 2\n \n- Piston Pin Type: Biconical\n \n- Kit Includes: Piston, pin, circlips, and piston rings\n \n- Special Coating: Some skirts feature molybdenum disulfide coating for reduced friction.\n \n- Ring Technology: Japanese-made rings with wear-resistant coatings (PVD or chromium nitride).\n \n- Net Weight: 0.39 Kg","weightGrams":null,"fitments":[{"make":"SUZUKI","model":"RM-Z 450","cc":null,"notes":null,"years":"2005–2007"}],"collections":[{"name":"Engine","url":"https://www.2brosparts.com/api/agent/collection/GB/engine"},{"name":"Pistons & Kits","url":"https://www.2brosparts.com/api/agent/collection/GB/pistons-kits"}],"links":{"page":"https://www.2brosparts.com/products/piston-kit-100mm-suzuki-rm-z-450-05-07-athena-s4f10000012b-490cc-big-bore","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/d200cc9bf270:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/d200cc9bf270:1"}},"market":{"country":"GB","countryName":"United Kingdom","locale":"en-gb","currency":"GBP","exchangeRateFromGbp":1,"pricesIncludeUkVat":true,"checkoutTax":null,"delivery":[{"name":"Standard","description":"Orders £15.00–£59.99 · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":4.99,"formatted":"£4.99"},"free":false,"minimumOrder":{"amount":0,"formatted":"£0.00","gbp":0},"weightGrams":null},{"name":"Standard","description":"Orders £60.00 and up · 2–4 business days","carrier":null,"estimatedDays":"2–4 business days","price":{"amount":0,"formatted":"£0.00"},"free":true,"minimumOrder":{"amount":60,"formatted":"£60.00","gbp":60},"weightGrams":null}],"storeUrl":"https://www.2brosparts.com"},"navigate":{"start":"https://www.2brosparts.com/api/agent","search":"https://www.2brosparts.com/api/agent/search/GB/{words+joined+with+plus}"},"howToBuy":{"summary":"Build a basket for the shopper and give them one checkout link.
