Manufactured using reverse extrusion and precision CNC machining, it ensures dimensional tolerances of less than 0.01mm. Made from a high-performance aluminum alloy with a high silicon content, this piston provides excellent resistance and reliability comparable to OEM components. It features a smooth profile for optimal flame propagation and reduced friction, with molybdenum disulfide coating on some skirts for enhanced performance. The piston rings, produced in Japan with wear-resistant coatings, ensure minimal friction and increased durability.\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eFeatures\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cbr\u003e\t\u003cli\u003eForged piston with an 81.95mm bore diameter\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eHigh-performance aluminum alloy with high silicon content\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eCNC-machined for precise tolerances under 0.01mm\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eMolybdenum disulfide-coated skirts (on select pistons) for reduced friction\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eDesigned for use with Athena Big Bore Cylinders\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003ePiston rings with wear-resistant coatings for durability\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eIncludes piston, pin, circlips, and piston rings\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eSpecifications\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cbr\u003e\t\u003cli\u003eBore Diameter: 81.95mm\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eCompression Height: 19.00mm\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eCompression Ratio: 13.1:1\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eDisplacement: 280cc\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eNet Weight: 0.23 kg\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eNumber of Segments: 2\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003ePiston Pin Diameter: 16x10x44.5mm\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003ePiston Type: Forged\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003ePiston Pin Type: Standard\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eCross-Reference OEM Part Numbers\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cbr\u003e\t\u003cli\u003eRings: S41316089\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e\u003cbr\u003e\u003cbr\u003e\u003cp\u003e\u003cstrong\u003eVehicle Fitments\u003c\/strong\u003e\u003c\/p\u003e\u003cbr\u003e\u003cbr\u003e\u003cul\u003e\n\u003cbr\u003e\t\u003cli\u003eHonda CRF250R (2004-2009)\u003c\/li\u003e\n\u003cbr\u003e\t\u003cli\u003eHonda CRF250X (2004-2015)\u003c\/li\u003e\n\u003cbr\u003e\n\u003c\/ul\u003e","brand":"ORO2U","offers":[{"title":"Default Title","offer_id":57138759532917,"sku":"56-K100.82.PIA","price":222.7,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0555\/5011\/6136\/files\/stock51506_1.jpg?v=1778201583","url":"https:\/\/www.smxoffroad.com\/products\/piston-kit-4-00mm-big-bore-82-00mm-honda-2004-2015-crf-r-x-athena-s5f08200001a","provider":"SMXOFFROAD Ltd","version":"1.0","type":"link"}
