Engineered for durability and precision, this 53.98mm Grade D piston is designed to meet the rigorous demands of two-stroke engine applications, providing optimal compression and consistent power delivery.\n\n### Advanced Manufacturing and Material Quality\n\nVertex pistons are crafted using specialized Low-Ex (low expansion) silicon-charged aluminum alloys, containing between 12% and 21% silicon depending on the specific application. These blanks are produced through advanced gravity casting or hydraulic forging processes, followed by a state-of-the-art automated heat treatment. This process refines the material structure to ensure superior strength and long-term reliability under high-stress conditions.\n\n### Precision Engineering and Surface Treatment\n\nTo ensure perfect tolerances, every piston is machined using the latest CNC technology and diamond-tipped tooling. This achieves specific surface finishes tailored for high-performance engine environments. Each component undergoes a rigorous multi-stage quality control process to guarantee consistency and craftsmanship.\n\n### Enhanced Durability Coatings\n\nThis piston features industry-leading surface enhancements to improve longevity and reduce internal wear:\n\n- Molybdenum Bisulphite Coating: A specialized black coating applied to aid in the break-in process and significantly reduce friction during cylinder operation.\n\n- Phosphate Coating: Incorporating developments from Formula One engine technology, this coating provides a slight increase in surface hardness and light porosity. This allows for superior adhesion of the Molybdenum coating, effectively doubling its durability and protecting the piston skirt over extended use.\n\n### Key Features\n\n- Grade D sizing at 53.98mm for precise engine clearances.\n\n- High-tech heat-treated aluminum alloy for maximum structural integrity.\n\n- CNC machined to exact specifications for optimal fit and function.\n\n- Advanced Molybdenum and Phosphate coatings to reduce friction and improve wear resistance.\n\n- Single ring design engineered for responsive engine performance.","weightGrams":null,"fitments":[],"collections":[],"links":{"page":"https://www.2brosparts.com/products/kawasaki-kx-125-1992-1993-grade-d-5398mm-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.
