Engineered for riders who demand superior power and reliability, this piston features a 14.9:1 compression ratio, specifically designed to optimize combustion efficiency and increase overall output.\n\n### Precision Engineering and Material Quality\n\nVertex pistons are manufactured using exotic Low-Ex silicon-charged aluminium alloys. Depending on the specific application, these alloys contain 12%, 18%, or 21% silicon to ensure thermal stability and reduce expansion. Each piston is produced through advanced gravity casting or hydraulic forging, followed by a state of the art heat treatment process in an automatic HT implant to refine the material structure for maximum durability.\n\n### Advanced Coating Technology\n\nTo ensure longevity and smooth operation, this piston is treated with high performance coatings:\n\n- Molybdenum Bisulphite Coating: A specialized black coating that assists during the critical break-in period and significantly reduces friction within the cylinder.\n\n- Phosphate Coating: Drawing inspiration from Formula One engine development, this all-over coating increases surface hardness. Its light porosity provides superior adhesion for the Molybdenum layer, effectively doubling the durability of the piston coating.\n\n### Key Features\n\n- High Compression Ratio: 14.9:1 for improved engine performance.\n\n- Precision Machining: Produced using the latest CNC technology and diamond tooling for exact tolerances and specific surface finishes.\n\n- Rigorous Quality Control: Every piston undergoes thorough manual and automatic inspection to meet the highest industry standards.\n\n- Size: 77.95mm diameter.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kxf-250-2020-grade-a-7795mm-high-compression-1491","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.
