Engineered for demanding 4-stroke applications, this kit provides superior strength and a precise fit, ensuring reliable power delivery for your ride.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eSpecifically designed for high-performance 4-stroke engines, this Athena Forged Piston Kit utilizes high-grade 2618 silicon aluminum, renowned for its exceptional strength and resistance to extreme temperatures and pressures. A crucial 3% copper additive further enhances heat dissipation, vital for sustained high-RPM operation and engine longevity. While Athena also produces 2-stroke pistons from 4032 silicon, this particular kit is tailored for 4-stroke powerplants.\u003c\/p\u003e\n\u003cp\u003eThe precision forging process creates an incredibly dense and uniform grain structure, resulting in a piston that is significantly stronger and lighter than conventional cast alternatives. This advanced tooling ensures the lightest possible product, contributing to improved throttle response, reduced reciprocating mass, and a more efficient engine. Each kit comes complete with an antiwear coated piston, high-quality steel rings, a durable piston pin, and secure circlips, providing everything needed for a comprehensive engine rebuild or upgrade. The meticulous manufacturing guarantees a perfect fit for a 76.97 mm bore with a 13.5:1 compression ratio, specifically for 250 cc 4-stroke engines, delivering the reliability and performance that enthusiasts demand.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh-Strength Forged Construction:\u003c\/strong\u003e Precision-forged from 2618 silicon aluminum, ensuring exceptional durability and resistance to extreme engine conditions for your 4-stroke 250cc engine.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnhanced Heat Resistance:\u003c\/strong\u003e Incorporates 3% copper for superior heat dissipation, crucial for maintaining performance and engine integrity during aggressive riding.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Lightweight Design:\u003c\/strong\u003e Advanced forging tooling results in the lightest possible piston, reducing reciprocating mass for improved throttle response and overall engine efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eComplete Rebuild Kit:\u003c\/strong\u003e Includes an antiwear coated piston, high-quality steel rings, a robust piston pin, and secure circlips, providing all essential components for a hassle-free engine refresh.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAntiwear Coated Piston:\u003c\/strong\u003e Features a specialized coating to minimize friction, reduce wear, and extend the lifespan of your engine components.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePrecision Fitment:\u003c\/strong\u003e Available in exact sizing, such as Standard Size B with a 76.97 mm diameter, ensuring a perfect, factory-like fit for your specific 4-stroke 250cc application.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eStyle: Forged Replica\u003c\/li\u003e\n\u003cli\u003eUnits: Kit\u003c\/li\u003e\n\u003cli\u003eEngine Type: 4-Stroke\u003c\/li\u003e\n\u003cli\u003eDisplacement: 250 cc\u003c\/li\u003e\n\u003cli\u003ePiston Diameter: 76.97 mm\u003c\/li\u003e\n\u003cli\u003ePiston Size: Standard Size B\u003c\/li\u003e\n\u003cli\u003ePiston Material: Forged Aluminum\u003c\/li\u003e\n\u003cli\u003eCompression Ratio: 13.5:1\u003c\/li\u003e\n\u003cli\u003eRing Material: Steel, Cast\u003c\/li\u003e\n\u003cli\u003eVendor Part Number: S5F07700005B\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Athena","offers":[{"title":"Default Title","offer_id":62381540868426,"sku":"09106557","price":174.95,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/334abe0b6b58dd5bee4057c9403468d1.webp?v=1781741753","url":"https:\/\/partsdenmark.com\/es\/products\/athena-forged-piston-kit-for-4-stroke-250cc-1","provider":"Parts Denmark","version":"1.0","type":"link"}
