Designed with an exclusive T-bridge architecture inspired by Formula 1 technology, this piston features a specialized racing profile that maximizes compression ratios without compromising the structural integrity of your engine.\n\nEach piston is forged from high-quality 2618 aluminum alloy, providing the necessary strength to withstand the extreme pressures and internal temperatures found in modern high-performance motorcycle engines. To ensure longevity and smooth operation, every Vertex piston is treated with a Molybdenum Disulphide (MOS2) coating on the skirt, which assists during the break-in process and significantly reduces friction and wear.\n\n### Key Features\n\n \n- GP Racers Choice Design: Features an exclusive T-bridge profile inspired by elite F1 engineering to optimize combustion efficiency.\n \n- Premium Construction: Forged from high-grade 2618 aluminum alloy for superior durability under high-stress conditions.\n \n- MOS2 Skirt Coating: Specialized Molybdenum Disulphide coating reduces friction, minimizes wear, and aids in the initial engine break-in period.\n \n- Precision Sizing: Vertex pistons are engineered with precise tolerances to ensure an ideal fit within the cylinder, effectively maximizing power output while reducing blow-by and oil consumption.\n \n- Optimized Compression: Specifically developed to deliver a high-performance 14.1:1 compression ratio for enhanced throttle response and power delivery.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/honda-crf-250r-250rx-2022-2023-grade-a-7896mm-gp-racers-choice-1411","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/5b8290e90817:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/5b8290e90817:1"}},"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.
