This high-quality piston kit is designed as a cost-effective alternative to standard HRC pistons, offering excellent value and reliability.\n\nEach kit includes a domed top piston, a 0.8mm flat ring, a wrist pin, and two clips, providing everything you need for a complete piston replacement.\n\n**Key Features:**\n\n \n- Forged construction for enhanced durability and performance.\n \n- Domed piston design for specific engine applications.\n \n- Includes a 0.8mm flat ring, wrist pin, and circlips.\n \n- All Vertex pistons undergo T-5 or T-6 hardening and tempering cycles for superior strength.\n \n- Manufactured in Italy to high standards.\n \n- OEM replacement quality, fitted as standard on many bikes.\n \n- Important Preparation Note: For optimal performance and longevity, it is crucial to properly prepare the piston by chamfering the skirt and ring groove, and setting the correct ring gap. Special attention should be paid to chamfering the rear port area as the ring gap is located at the back to run over the rear boost port.\n \n- Ring Replacement Recommendation: To prevent potential issues with the ring locating tag breaking, it is recommended to change the ring halfway through the piston's typical life cycle (300 to 350 KM).\n\n**Specifications:**\n\n \n- Bore Size: 54.00mm (Piston actual size 53.94mm)\n\n**Included Components:**\n\n \n- Piston\n \n- Ring\n \n- Wrist Pin\n \n- Circlips","weightGrams":null,"fitments":[{"make":"HONDA","model":"RS 125","cc":null,"notes":null,"years":"2003–2007"},{"make":"HONDA","model":"RS GP DOMED 125","cc":null,"notes":null,"years":"2003–2007"}],"collections":[{"name":"Engine","url":"https://www.2brosparts.com/api/agent/collection/GB/engine"},{"name":"Pistons & Kits","url":"https://www.2brosparts.com/api/agent/collection/GB/pistons-kits"}],"links":{"page":"https://www.2brosparts.com/products/piston-kit-gp-domed-540-a-rs125-03-09-vertex-23105a-gp-honda","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/bd4b74142b72:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/bd4b74142b72:1"}},"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.
