Precision engineered for demanding applications, this piston is manufactured using advanced Low-Ex aluminium alloy containing high silicon content to ensure optimal thermal expansion control and structural integrity.\n\nVertex pistons are produced using sophisticated gravity casting or hydraulic forging processes. Each component undergoes a specialized heat treatment cycle in an automated implant, providing a refined material structure that enhances durability and reliability under extreme operating conditions.\n\n### Advanced Engineering and Surface Finishing\n\nThe manufacturing process utilizes state-of-the-art CNC machinery and diamond-tipped tooling to achieve exacting tolerances and specific surface finishes. To further enhance performance and longevity, this piston features a dual-layer coating system:\n\n- Molybdenum Bisulphite Coating: A high-performance black coating designed to reduce friction during operation and assist significantly during the initial piston break-in period.\n\n- Phosphate Coating: Inspired by Formula One engine technology, this layer provides a slight increase in surface hardness and creates a light porosity that ensures superior adhesion of the Molybdenum coating, effectively doubling its durability.\n\n### Key Features\n\n- Designed for 53.97mm bore applications\n\n- Single ring configuration for high-revving efficiency\n\n- Exotic silicon-charged aluminium alloy construction\n\n- Cutting-edge heat treatment for improved fatigue resistance\n\n- Precision CNC-machined for a perfect fit\n\n- Rigorous manual and automatic quality control inspections","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/suzuki-rm-125-1990-1999-grade-c-5397mm-single-ring-piston","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.
