Engineered for precision and longevity, this 54.45mm (+0.50mm oversize) single ring piston is designed to meet the rigorous demands of high-performance two-stroke engines.\n\n### Advanced Manufacturing and Material Quality\n\nVertex pistons are crafted from specialized Low-Ex (low expansion) aluminum alloys containing a precise silicon content of 12%, 18%, or 21% based on the application. These blanks are produced using either gravity casting or hydraulic forging, followed by a sophisticated heat treatment process in an automatic HT implant. This ensures a refined material structure that delivers superior strength and heat resistance.\n\n### Precision Machining and Surface Coatings\n\nEvery piston is machined using state-of-the-art CNC technology and diamond-tipped tools to achieve exact surface finishes tailored for optimal cylinder interaction. To maximize durability and performance, this piston features two critical protective layers:\n\n \n- Molybdenum Bisulphite Coating: A specialized black coating that reduces friction during the critical engine break-in period and throughout daily operation.\n \n- Phosphate Coating: Drawing from Formula One engine development, this coating provides increased hardness and surface porosity. This serves as a base to improve the adhesion and durability of the Molybdenum coating, effectively doubling the lifespan of the protective layer.\n\n### Key Features\n\n \n- Engineered for precise +0.50mm oversize specifications (54.45mm diameter).\n \n- Single ring design for high-revving performance.\n \n- Rigorous manual and automatic quality control testing for maximum reliability.\n \n- Advanced coatings to resist wear and minimize internal friction.\n \n- Constructed with high-tech materials to manage thermal expansion and engine stress.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-125-1995-1997-050mm-oversize-5445mm-single-ring-replica-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/a0c2385e5f94:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/a0c2385e5f94:1"}},"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.
