Engineered to meet exacting specifications, this 66.34mm piston offers precision sizing and superior durability for demanding riding conditions. Vertex pistons are renowned for their high-quality construction and are a top choice for riders looking for reliable power delivery and engine longevity.\n\n### Advanced Manufacturing and Material Quality\n\nVertex utilizes advanced Low-Ex (low expansion) aluminum alloys with precise silicon content to ensure thermal stability and strength. The manufacturing process employs both gravity casting and hydraulic forging, followed by a sophisticated heat treatment process that refines the material structure for maximum resistance to wear and fatigue. Every piston is machined using high-precision CNC technology and diamond tooling to achieve exact tolerances and specific surface finishes.\n\n### Engineered for Performance and Durability\n\nTo minimize friction and ensure a smooth break-in period, this piston features a Molybdenum Bisulphite black coating. This is further enhanced by an innovative Phosphate Coating, developed from Formula One engine technology. This additional layer provides a slight hardness increase and a porous surface that improves the adhesion of the Molybdenum coating, resulting in significantly extended durability and reduced internal drag.\n\n### Key Features\n\n \n- Precision Engineering: Manufactured for an exact fit and optimal compression.\n \n- Advanced Alloy Construction: High-silicon Low-Ex aluminum for superior heat resistance.\n \n- Enhanced Coatings: Molybdenum Bisulphite coating reduces friction and assists with initial break-in.\n \n- Extended Coating Life: Integrated Phosphate Coating provides superior adhesion and longevity for the friction-reducing layer.\n \n- Rigorous Quality Control: Every unit undergoes strict manual and automatic inspections to ensure the highest standards of reliability.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-250-1998-grade-a-6634mm-twin-ring-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/3be962fa6637:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/3be962fa6637:1"}},"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.
