Engineered in Germany, this piston is designed for superior strength, durability, and optimal thermal efficiency. The forged construction provides increased resilience under high stress, while the advanced design promotes effective heat transfer from the combustion chamber to the cylinder walls, crucial for maintaining peak engine performance.\n\nThe piston features an innovative elliptical design that ensures a uniform bearing surface as the piston expands and contracts with temperature changes. This intelligent design minimizes localized stress and significantly reduces the risk of piston collapse, contributing to a longer engine life.\n\n#### Key Features:\n\n\t\n- Forged piston for superior strength and reliability.\n\t\n- Designed for optimal combustion heat transfer.\n\t\n- Elliptical shape promotes even thrust load distribution and reduces stress.\n\t\n- Precision manufactured in Germany for exceptional quality.\n\n#### Specifications:\n\n\t\n- Bore Size: 67.00 mm\n\t\n- Actual Piston Diameter: 66.94 mm\n\t\n- Displacement (cm&sup3;): 246\n\t\n- Stroke: 72.00 mm\n\t\n- Piston Clearance: 0.06 mm\n\t\n- Compression Height: 38.00 mm\n\t\n- Compression Ratio (2-Stroke): Specific to Wossner and OEM configurations.\n\n#### Included Components:\n\n\t\n- Wossner Piston Part Number: 8156D100\n\t\n- Lock Ring Part Number: CW18\n\t\n- Pin Part Number: WP033\n\t\n- Ring Set Part Number: RSB6700 (x2)","weightGrams":null,"fitments":[{"make":"HONDA","model":"ATC R 250","cc":null,"notes":null,"years":"1985–1986"},{"make":"HONDA","model":"CR 250","cc":null,"notes":null,"years":"1984–1985"},{"make":"HONDA","model":"TRX 250","cc":null,"notes":null,"years":"1985–1989"}],"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-84-85-cr250-6700-wossner-8156d100-honda-mx","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/07fa4ee25e60:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/07fa4ee25e60:1"}},"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.
