Designed for 1997-2001 models, this kit features a standard bore size of 67.40mm and is manufactured in Germany using advanced forging techniques.\n\nThe piston's unique elliptical design is crucial for managing thermal expansion. By distributing stress evenly across the piston, it prevents localized pressure points and the risk of piston collapse, especially under demanding operating conditions. This intelligent design also optimizes heat transfer from the combustion chamber to the cylinder wall, ensuring consistent performance and extended component life.\n\n#### Key Features:\n\n\t\n- Forged piston construction for superior strength and wear resistance.\n\t\n- Elliptical shape promotes even thermal expansion.\n\t\n- Reduces the likelihood of piston collapse by uniformly distributing thrust loads.\n\t\n- Optimized for efficient heat dissipation from the combustion area.\n\t\n- Precision engineered and manufactured in Germany.\n\n#### Specifications:\n\n\t\n- Bore Size: 67.40mm (Standard)\n\t\n- Actual Piston Diameter: 66.34mm\n\t\n- Compression Height: 38.00mm\n\t\n- Stroke: 72.00mm\n\t\n- Displacement: 249 cm&sup3;\n\t\n- Recommended Piston Clearance: 0.06mm\n\t\n- Compression Ratio: Compatible with 2-stroke applications (Wossner and OEM specifications).\n\n#### Included Components:\n\n\t\n- Wossner Piston Kit Part Number: 8001DA\n\t\n- Lock Ring: CW18\n\t\n- Piston Pin: WP033\n\t\n- Ring Set: RSB6640 (x2)\n\t\n- Connecting Rod: P2021\n\t\n- Cross-Reference OEM Part Number: 13101-KZ3-L10","weightGrams":null,"fitments":[{"make":"HONDA","model":"CR 2 RING 250","cc":null,"notes":null,"years":"1997–2001"},{"make":"HONDA","model":"CR 250","cc":null,"notes":null,"years":"1997–2001"},{"make":"HONDA","model":"CR 250R","cc":null,"notes":null,"years":"1997–2001"},{"make":"HUSQVARNA","model":"CR 250","cc":null,"notes":null,"years":"1998–2013"},{"make":"HUSQVARNA","model":"WR 250","cc":null,"notes":null,"years":"1998–2013"},{"make":"SUZUKI","model":"RM 250","cc":null,"notes":null,"years":"1998"}],"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-97-01-cr250-6640-a-wossner-8001da-honda-mx","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/e924e5ec8710:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/e924e5ec8710:1"}},"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.
