Engineered for precision and longevity, this 66.37mm Grade C twin ring piston is designed to meet the rigorous demands of high-performance off-road engines.\n\n### Advanced Engineering and Materials\n\nVertex pistons are manufactured using exotic Low-Ex silicon-charged aluminium alloys, with silicon content specifically calibrated for each application. Utilizing either gravity casting or hydraulic forging processes, each piston blank undergoes a sophisticated heat treatment in an automatic HT implant. This process ensures a refined material structure that delivers exceptional strength and thermal stability.\n\n### Precision Manufacturing\n\nEvery piston is machined using state-of-the-art CNC technology and diamond tooling. This high-tech approach allows for specific surface finishes optimized for your engine's requirements. Before leaving the factory, each unit undergoes a comprehensive manual and automatic quality control inspection to ensure it meets the highest industry standards.\n\n### Enhanced Coatings for Reduced Friction\n\nTo ensure peak performance, this piston features a dual-layer coating system:\n\n- Molybdenum Bisulphite Coating: A specialized black coating that assists during the break-in period and significantly reduces friction during operation.\n\n- Phosphate Coating: Drawing from Formula One engine technology, this all-over coating increases surface hardness and provides light surface porosity. This creates superior adhesion for the Molybdenum layer, effectively doubling the durability of the coating.\n\n### Key Features\n\n- Size: 66.37mm Grade C\n\n- Design: Twin ring configuration for improved seal and stability\n\n- Material: High-grade Low-Ex silicon-charged aluminium alloy\n\n- Durability: Phosphate coated for extended wear resistance\n\n- Performance: Friction-reducing Molybdenum Bisulphite finish","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-250-2005-2008-grade-c-6637mm-twin-ring-piston","buyOneNow":null,"basketWithThis":null}},"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.
