Racers Choice piston. Engineered for competitive applications, this 77.95mm Grade A piston features a high 14.6:1 compression ratio, designed to deliver maximum power and throttle response for serious riders and racers.\n\nVertex pistons are crafted from advanced Low-Ex silicon-charged aluminum alloys, utilizing either gravity casting or hydraulic forging processes. The structural integrity of the material is refined through a sophisticated, automated heat treatment process, ensuring exceptional durability and resistance under high-stress conditions.\n\n### Advanced Engineering and Coatings\n\nPrecision is at the heart of the Vertex manufacturing process. Each piston is machined on state of the art CNC equipment using diamond tools to achieve specific surface finishes tailored to high-performance demands. Every unit undergoes rigorous manual and automatic quality control to ensure it meets the highest standards.\n\nTo enhance performance and longevity, this piston features dual-layer protection:\n\n \n- Molybdenum Bisulphite Coating: A specialized black coating that assists during the break-in process and significantly reduces friction within the cylinder.\n \n- Phosphate Coating: Drawing inspiration from Formula One technology, this all-over surface treatment provides increased hardness and light surface porosity. This ensures superior adhesion for the Molybdenum layer, effectively doubling the durability of the coating.\n\n### Key Features\n\n \n- High compression 14.6:1 ratio for increased power output.\n \n- Engineered using exotic Low-Ex silicon-charged aluminum alloys.\n \n- Advanced heat treatment process for superior material refinement.\n \n- Precision CNC machined for consistent, high-performance tolerances.\n \n- Enhanced friction reduction through Molybdenum Bisulphite and Phosphate surface coatings.\n \n- Rigorously tested to meet professional racing standards.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kxf-250-2020-grade-a-7795mm-gp-racers-choice-1461","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.
