This premium \u003cstrong\u003eWiseco YZ 80 Piston Kit Standard Bore\u003c\/strong\u003e is meticulously forged from high-silicon aluminum alloy, ensuring unparalleled strength and reliability for both trail and racing applications.\u003c\/p\u003e\n\u003ch2\u003eDescription\u003c\/h2\u003e\n\u003cp\u003eDesigned to deliver a significant boost in performance, this high-performance motorcycle piston kit provides exceptional durability, longevity, and increased horsepower. The innovative forging design, combined with an optimized piston skirt, works in harmony to maximize both horsepower and torque output across the rev range. Wiseco's commitment to advanced engineering is evident in the ultra-stiff strutted forgings and titanium nitride-coated rings, which contribute to sustained power delivery and extended service life. Each piston in this assembly is E-Coated on the crown, ring grooves, and pin bore, offering superior wear resistance and protection against micro-welding, galling, and detonation, critical for high-stress environments. GP Series parts, like this one, feature reduced external machining to enhance bore sealing for increased compression. Furthermore, the removal of boost ports helps to create a more predictable powerband, providing a stronger pull in the top end, making it an ideal choice for expert racers and tuners seeking a competitive edge for their Yamaha YZ 80 engine rebuild.\u003c\/p\u003e\n\u003ch2\u003eFeatures \u0026amp; Highlights\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eForged High-Silicon Aluminum Alloy:\u003c\/strong\u003e Constructed for maximum strength and dependability, ensuring your engine can withstand the rigors of high-performance riding and racing.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eIncreased Horsepower \u0026amp; Torque:\u003c\/strong\u003e Innovative piston design and skirt geometry are engineered to optimize engine output, delivering noticeable gains in both power and torque.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eEnhanced Durability \u0026amp; Longevity:\u003c\/strong\u003e Features like ultra-stiff strutted forgings and titanium nitride-coated rings contribute to a longer lifespan and consistent performance, even under demanding conditions.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eE-Coated for Superior Protection:\u003c\/strong\u003e The piston's crown, ring grooves, and pin bore are E-Coated to provide exceptional wear resistance, preventing micro-welding, galling, and detonation.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eOptimized Compression \u0026amp; Powerband:\u003c\/strong\u003e GP Series design minimizes external machining for better bore sealing and compression, while removed boost ports ensure a more predictable and powerful top-end pull.\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eComplete Kit for Rebuilds:\u003c\/strong\u003e Includes all essential components: the high-tech forged piston, rings, wrist pin, and circlips, simplifying your engine rebuild process.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Wiseco\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003ePiston Type:\u003c\/strong\u003e High-Performance Forged\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eBore Size:\u003c\/strong\u003e Standard (STD.)\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eConstruction Material:\u003c\/strong\u003e High-Silicon Aluminum Alloy\u003c\/li\u003e\n    \u003cli\u003e\n\u003cstrong\u003eFitment:\u003c\/strong\u003e Yamaha YZ 80, YZ 80 LW (1985-1999)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEAN:\u003c\/strong\u003e 0193564134011\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eImportant to Know\u003c\/h2\u003e\n\u003cul\u003e\n    \u003cli\u003eCylinder sleeves must be purchased separately.\u003c\/li\u003e\n    \u003cli\u003eService intervals may be increased with Racer's Choice pistons over conventional Wiseco pistons, and are for expert racers and tuners only.\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Wiseco","offers":[{"title":"Default Title","offer_id":63702412099914,"sku":"520M04800","price":599.0,"currency_code":"PLN","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0971\/0016\/9546\/files\/41e149cc59002bbe5e4d6aaae0be6882.webp?v=1790486277","url":"https:\/\/partsdenmark.pl\/products\/wiseco-high-performance-piston-kit-standard-bore-for-yamaha-yz","provider":"Parts Denmark","version":"1.0","type":"link"}
