Designed specifically for 2-stroke applications, this piston is engineered for optimal heat transfer from the combustion chamber to the cylinder walls, contributing to improved overall efficiency. Its unique elliptical design ensures a uniform bearing surface even under heat expansion. This feature helps to reduce localized pressure and distribute thrust loads evenly, preventing premature piston collapse and extending the life of your engine components.\n\n**Key Features:**\n\n \n- Forged Construction: Provides superior strength and durability compared to cast pistons, handling higher stresses and temperatures.\n \n- Optimized Heat Transfer: Engineered to efficiently move heat away from the combustion chamber, promoting better performance and reliability.\n \n- Elliptical Design: The precisely shaped piston skirt maintains a consistent bearing surface under thermal expansion, preventing uneven wear and potential failure.\n \n- Single-Ring Configuration: Reduces internal friction, leading to improved throttle response and power output.\n \n- German Engineering: Manufactured in Germany, ensuring high standards of quality and precision.\n\n**Specifications:**\n\n \n- Bore: 55.95 mm\n \n- Piston Size: 56.00 mm\n \n- Displacement: 144 cm&sup3;\n \n- Stroke: 58.50 mm\n \n- Clearance: 0.05 mm\n \n- Compression Height: 29.50 mm\n\n**Included Components:**\n\n \n- Lock: CW15\n \n- Pin: WP032\n \n- Ring Set: RSB5600\n \n- Rod: P2012","weightGrams":null,"fitments":[{"make":"KTM","model":"144 SX","cc":null,"notes":null,"years":"2007–2008"},{"make":"KTM","model":"150 SX","cc":null,"notes":null,"years":"2009–2015"},{"make":"KTM","model":"150 XC","cc":null,"notes":null,"years":"2010–2015"},{"make":"KTM","model":"150 XC-W","cc":null,"notes":null,"years":"2010–2015"}],"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-ktm-sx144-150-56-a-forged-wossner-8222da-51530007400","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.
