Designed specifically for the Suzuki RGV 250, this Grade D single-ring piston measures 55.97mm and is crafted to meet the highest standards of durability and efficiency for high-revving two-stroke applications.\n\n### Advanced Manufacturing and Material Quality\n\nVertex utilizes exotic Low-Ex (low expansion) aluminum alloys charged with high levels of silicon. Depending on the specific application, these alloys provide the optimal balance of strength and thermal stability. The manufacturing process employs both gravity casting and hydraulic forging to create blanks that are then refined through a sophisticated automated heat treatment process to ensure maximum material integrity.\n\n### Precision Machining and Surface Technology\n\nEach piston is machined using state-of-the-art CNC technology and diamond-tipped tooling to achieve the exact surface finish required for superior performance. To minimize friction and assist during the critical engine break-in period, these pistons feature a specialized Molybdenum Bisulphite coating.\n\n### Enhanced Durability with Phosphate Coating\n\nInspired by advanced Formula One engine developments, these pistons are treated with an all-over Phosphate coating. This treatment offers two distinct advantages:\n\n \n- Increased Hardness: Provides a slight boost in surface hardness for improved wear resistance.\n \n- Superior Adhesion: The light surface porosity allows the Molybdenum coating to bond more effectively, effectively doubling the durability of the protective friction-reducing layer.\n\n### Key Features\n\n \n- Grade D piston with a 55.97mm diameter.\n \n- Engineered for high-performance two-stroke operation.\n \n- Advanced Molybdenum Bisulphite coating to reduce internal cylinder friction.\n \n- Phosphate coating for long-lasting finish and enhanced adhesion.\n \n- Rigorous manual and automatic quality control for professional-grade reliability.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rgv-250-grade-d-5597mm-single-ring","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.
