Designed for Athena Big Bore Cylinders, this kit is crafted from a special high-performance aluminum alloy with a high silicon content, ensuring the reliability of original equipment while providing enhanced resistance and superior performance. Produced using advanced CNC machining tools, this piston offers dimensional tolerances of less than 0.01 mm for precision engineering.\n\nThe piston features a perfectly smooth profile for regular flow and optimal flame propagation. Some piston skirts are treated with a molybdenum disulfide coating, applied by screen printing, to further reduce friction, boost performance, and extend durability. Each piston is engineered in Italy and rigorously tested on dynamometer benches and on the track to validate its performance in extreme conditions.\n\nThis piston kit includes the piston, pin, circlips, and piston rings. The piston rings are produced in Japan with wear-resistant coatings (PVD or chromium nitride) to increase retention and durability, ensuring they adapt perfectly to the cylinder liner even at low tangential load. All components are replaceable and interchangeable.\n\n#### Key Features:\n\n \n- Piston Type: Forged for superior strength and performance.\n \n- Big Bore Application: Designed for Athena Big Bore Cylinders.\n \n- Material: Special high-performance aluminum alloy with high silicon content.\n \n- Precision Machining: CNC machined with dimensional tolerances of less than 0.01 mm.\n \n- Friction Reduction: Some skirts feature a molybdenum disulfide coating.\n \n- High-Quality Rings: Made in Japan with wear-resistant coatings (PVD or chromium nitride).\n \n- Complete Kit: Includes piston, pin, circlips, and piston rings.\n \n- Engineered and Tested: Designed in Italy and validated under extreme conditions.\n\n#### Technical Specifications:\n\n \n- Bore Diameter: 82.95 mm\n \n- Compression Height: 17.70 mm\n \n- Compression Ratio: 13.5:1\n \n- Number of Segments: 2\n \n- Piston Pin Type: Biconical\n \n- Big End Pin Diameter: 16x8.5x44 mm\n \n- Net Weight: 0.23 Kg","weightGrams":null,"fitments":[{"make":"HUSQVARNA","model":"SMR 250","cc":null,"notes":null,"years":"2006–2009"},{"make":"HUSQVARNA","model":"TC 250","cc":null,"notes":null,"years":"2006–2009"},{"make":"HUSQVARNA","model":"TE 250","cc":null,"notes":null,"years":"2006–2009"},{"make":"HUSQVARNA","model":"TE 310","cc":null,"notes":null,"years":"2010"},{"make":"HUSQVARNA","model":"TXC 250","cc":null,"notes":null,"years":"2006–2009"},{"make":"KAWASAKI","model":"KX 250F","cc":null,"notes":null,"years":"2004–2019"},{"make":"SUZUKI","model":"RM-Z 250","cc":null,"notes":null,"years":"2004–2018"},{"make":"YAMAHA","model":"WR 250F","cc":null,"notes":null,"years":"2001–2012"},{"make":"YAMAHA","model":"WR R 250","cc":null,"notes":null,"years":"2008–2017"},{"make":"YAMAHA","model":"WR X 250","cc":null,"notes":null,"years":"2008–2017"},{"make":"YAMAHA","model":"YZ 250F","cc":null,"notes":null,"years":"2001–2007"}],"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-a-83mm-suz-rm-zkaw-kx-250-07-22-athena-s5f08300005a-290cc-big-bore-ki","buyOneNow":"https://www.2brosparts.com/api/agent/checkout/GB/74f98294e289:1","basketWithThis":"https://www.2brosparts.com/api/agent/basket/GB/74f98294e289:1"}},"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.
