Designed for riders who demand reliability and power, this 66.34mm piston is manufactured to meet rigorous quality standards, ensuring an ideal fit and superior performance for your motorcycle engine.\n\n### Advanced Manufacturing Technology\n\nVertex utilizes exotic Low-Expansion (Low-Ex) silicon-charged aluminium alloys to create these pistons. The material composition, containing 12%, 18%, or 21% silicon depending on the application, ensures exceptional thermal stability and durability. The production process involves sophisticated gravity casting or hydraulic forging, followed by a state-of-the-art heat treatment in an automated implant to refine the material structure for maximum strength.\n\n### Precision Engineering and Durability\n\nEach piston is finished using cutting-edge CNC machinery and diamond-tipped tooling to achieve the exact surface specifications required for high-performance use. To further enhance longevity, every unit features a dual-layer coating system:\n\n \n- Molybdenum Bisulphite Coating: A high-performance black coating that assists with the initial break-in period and significantly reduces friction during operation.\n \n- Phosphate Coating: Borrowing technology from Formula One engines, this all-over coating increases surface hardness and provides a light porosity that ensures superior adhesion of the Molybdenum layer, effectively doubling the coating durability.\n\n### Key Features\n\n \n- Precision Diameter: 66.34mm Grade A sizing for accurate clearance.\n \n- Twin Ring Design: Engineered to provide an excellent seal and consistent compression.\n \n- Rigorous Quality Control: Every piston undergoes extensive manual and automated inspections to ensure it meets the highest industry benchmarks.\n \n- Friction Reduction: Specialized coatings minimize wear and heat buildup, extending the life of both your piston and cylinder.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-250-1996-1997-grade-a-6634mm-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.
