Manufactured with a high-silicon content hypereutectic cast aluminum material, it offers reduced heat expansion, tighter clearances, increased hardness, and a longer lifespan with reduced scuffing.\n\nThe piston features a machined, smooth piston crown designed to minimize carbon buildup, thereby increasing horsepower and improving fuel economy. For enhanced durability and minimal expansion, the crowns are hard anodized, making them 75% stronger than non-anodized versions and reducing the risk of cold seizures. This is further complemented by Teflon/Molybdenum coated skirts (MOS2) which significantly reduce friction and heat for added power and extended engine life.\n\nNamura piston rings are designed to match OEM specifications, with available fractional oversize pistons to extend the life of your cylinder by renewing original clearances if slightly worn, avoiding costly sleeving.\n\n \n- Bore Size: 67.50mm\n \n- Oversize: 1.00mm\n \n- Material: High-silicon content hypereutectic cast aluminum\n \n- Piston Crown: Machined, smooth finish for reduced carbon buildup\n \n- Piston Crown Coating: Hard anodized for increased strength and minimal expansion\n \n- Piston Skirt Coating: MOS2 (Teflon/Molybdenum) for reduced friction and heat\n \n- Rings: Match OEM design\n \n- Engineered in: USA\n \n- Manufactured in: Taiwan","weightGrams":null,"fitments":[],"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-97-01-cr250-6750-namura-nx-10025-4-husqvarna","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/52e539c970f3:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/52e539c970f3:1"}},"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.
