Designed for demanding applications, this piston is constructed from premium Low-Expansion (Low-Ex) silicon-charged aluminium alloys, providing superior thermal stability under extreme engine temperatures.\n\nEach piston undergoes a sophisticated gravity casting or hydraulic forging process, followed by a precision heat treatment in an automated implant. This ensures a refined material structure capable of withstanding the rigors of high-revving engine environments. The final machining is performed on state-of-the-art CNC equipment using diamond tooling to achieve exact surface finishes tailored for optimal performance.\n\n**Key Features:**\n\n \n- Advanced Alloy Composition: Manufactured with 12%, 18%, or 21% silicon content depending on the specific engine requirements for enhanced strength.\n \n- Phosphate Coating: Features an all-over phosphate coating that increases surface hardness and provides light porosity, significantly improving the adhesion of the anti-friction layer.\n \n- Molybdenum Bisulphite Finish: Coated with Molybdenum Bisulphite to reduce internal friction and facilitate a smoother engine break-in process.\n \n- Enhanced Durability: The combination of advanced coating technology doubles the durability of the anti-friction layer compared to standard pistons.\n \n- Quality Assured: Every unit passes through rigorous manual and automatic quality control inspections to meet the highest standards of precision and reliability.\n\nWhether you are performing a routine rebuild or seeking a performance upgrade, this Vertex twin ring piston offers the engineering excellence required to maintain peak power output and engine longevity.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-250-2000-2002-grade-a-6634mm-twin-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/4dcf419ce489:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/4dcf419ce489:1"}},"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.
