Vertex pistons are manufactured using either a gravity cast or hydraulic forging process to make the blank parts and then the material structure is refined using a hi-tech Heat Treatment completed in an automatic HT implant with solubilization by quench in hot water. This heat treating process is cutting edge technology for this type of aluminium alloys. The machining process is completed using the latest CNC machines and software as well as the usage of diamond tools.

Designed for riders who demand reliability and power, this piston is manufactured using advanced metallurgical techniques to ensure optimal strength and durability under high-stress racing conditions.\n\n### Advanced Manufacturing and Material Quality\n\nVertex pistons are crafted from high-grade Low-Ex aluminum alloys, specifically formulated with a high silicon content to reduce thermal expansion. Through a sophisticated gravity cast or hydraulic forging process, these pistons achieve a refined material structure. This process is further enhanced by cutting-edge heat treatment technology, ensuring the structural integrity of the component during intense engine cycles.\n\n### Precision Engineering and Durability\n\nEach piston is machined on state-of-the-art CNC equipment utilizing diamond-tipped tools to achieve precise surface finishes tailored for high-performance applications. To ensure superior longevity, the piston features a Molybdenum Bisulphite black coating, which assists during the break-in period and significantly reduces friction within the cylinder.\n\nFurthermore, this piston incorporates an advanced phosphate coating. Inspired by Formula One technology, this coating provides increased surface hardness and light porosity, which improves the adhesion and durability of the Molybdenum finish, allowing it to last twice as long as standard coatings.\n\n### Key Features\n\n \n- High-Silicon Aluminum Alloy: Low expansion material for consistent performance and tighter tolerances.\n \n- Optimized Surface Finish: Precision machined using diamond tools for specific application requirements.\n \n- Molybdenum Bisulphite Coating: Reduces friction and protects the piston during the critical break-in phase.\n \n- Phosphate Coating: Enhanced hardness and superior coating adhesion for increased durability.\n \n- Rigorous Quality Control: Every unit undergoes strict manual and automatic inspection processes to meet the highest industry standards.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-250-2003-2012-grade-a-6634mm-single-ring-race-piston","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/21f76c444555:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/21f76c444555:1"}},"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.
