Designed as a 1.6mm oversize component with a 67.95mm diameter, this twin ring piston is manufactured using advanced metallurgical techniques to ensure optimal operation under demanding conditions.\n\nVertex pistons are crafted from high quality Low-Ex (low expansion) silicon-charged aluminium alloys. Through a combination of gravity casting or hydraulic forging and a sophisticated heat treatment process, these pistons achieve a refined material structure that delivers exceptional strength and stability.\n\nPrecision is at the heart of the Vertex manufacturing process. Every unit is machined using state of the art CNC technology and diamond tooling to achieve the exact surface finish required for high performance applications. To ensure longevity and smooth operation, each piston features a Molybdenum Bisulphite black coating, which assists during the break in period and reduces internal friction. Additionally, the integrated phosphate coating increases surface hardness and improves the adhesion of the Molybdenum layer, effectively doubling the durability of the coating.\n\n### Key Features\n\n- 1.6mm oversize (67.95mm diameter) for precision engine rebuilding.\n\n- Twin ring design for consistent compression and performance.\n\n- Constructed from high-grade Low-Ex silicon-charged aluminium alloys.\n\n- Heat treated for enhanced material integrity and thermal resistance.\n\n- Precision machined via CNC technology for exact tolerances.\n\n- Molybdenum Bisulphite coating to reduce friction and improve break in.\n\n- Phosphate coating for superior durability and wear resistance.\n\n- Rigorous manual and automatic quality control testing.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-cr-250-1989-1994-16mm-oversize-6795mm-twin-ring-replica","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/d63162240e0c:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/d63162240e0c: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.
