Engineered for precision and longevity, this Grade C piston features a 66.37mm diameter and a twin ring design to provide optimal compression and consistent power delivery throughout the RPM range.\n\n### Advanced Material Technology\n\nVertex pistons are constructed using exotic Low-Ex (low expansion) silicon-charged aluminium alloys. Through a combination of gravity casting or hydraulic forging and a sophisticated heat-treatment process, these pistons achieve superior material density and structural integrity, ensuring they withstand the rigors of high-performance use.\n\n### Precision Engineering and Coatings\n\nEvery piston is machined using state-of-the-art CNC technology and diamond tooling for exact tolerances and specific surface finishes. To ensure maximum durability, this piston includes:\n\n- Molybdenum Bisulphite Coating: A specialized black coating that aids in the break-in process and significantly reduces internal friction.\n\n- Phosphate Coating: Borrowing technology from Formula One engines, this all-over coating increases surface hardness and provides light porosity for superior Molybdenum adhesion, effectively doubling the durability of the protective layer.\n\n### Key Features\n\n- Grade C sizing at 66.37mm\n\n- Twin ring configuration for enhanced sealing\n\n- High-tech heat treatment for refined material structure\n\n- Rigorous manual and automatic quality control inspections\n\n- Designed for reduced friction and extended component life","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-250-1992-1997-grade-c-6637mm-twin-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/ae09140b6e37:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/ae09140b6e37:1"}},"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.
