Designed with an exclusive T-bridge architecture inspired by Formula 1 technology, this piston features a specialized racing profile that optimizes compression ratios without compromising the structural integrity of your engine.\n\n### Advanced Engineering and Construction\n\nEach Vertex piston is precision forged from high-quality 2618 aluminum alloy. This material selection ensures that the component can withstand the intense pressures and high thermal loads found in modern high-performance engines. To ensure longevity and smoother operation, the piston skirt is finished with a Molybdenum Disulphide (MOS2) coating. This advanced coating reduces friction during the break-in process and continues to minimize wear throughout the service life of the piston.\n\n### Key Features\n\n \n- GP Racers Choice Design: Features a race-proven T-bridge design for enhanced strength and performance.\n \n- Premium Materials: Forged from 2618 aluminum alloy to offer superior resistance to fatigue and high engine pressures.\n \n- MOS2 Skirt Coating: Specialized Molybdenum Disulphide coating reduces internal friction and wear.\n \n- Precision Tolerances: Crafted with exacting dimensions to ensure an ideal fit within the cylinder.\n \n- Optimized Compression: Specifically profiled to maximize power output and engine response.\n \n- Performance Focused: Designed to reduce blow-by and minimize oil consumption for consistent engine efficiency.\n\nWhether you are competing on the track or pushing your machine to its limits, the Vertex GP Racers Choice piston provides the durability and power gains required for competitive riding environments.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-crf-250r-250rx-2022-2023-grade-b-7897mm-gp-racers-choice-1411","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/fd50c4595e07:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/fd50c4595e07:1"}},"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.
