Benefits include increased heat transfer, reduced friction and helping to eliminate cold seizures. Machined Smooth Heads - Reflects combustion heat and reduces carbon buildup, protecting the top of the piston. Some tests have shown this feature can increase horsepower and fuel economy by up to 6%. Anodized Domes - Increases heat resistance and durability; pistons with anodized domes are 75% stronger than non-anodized pistons. Hypereutectic Casting Process - Provides higher silicon content for reduced expansion rates and additional wear resistance; it also has an ability to withstand higher cylinder temperatures.\u003cbr\u003e\u003cbr\u003eVehicle Fitment:\u003cbr\u003e\u003cbr\u003e1999-2022 Yamaha YZ250\u003cbr\u003e 2022 Yamaha YZ250 Monster Energy Yamaha Racing Edition\u003cbr\u003e 2016-2022 Yamaha YZ250X","brand":"Namura Technologies","offers":[{"title":"Default Title","offer_id":44121657180282,"sku":"4914794","price":82.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/8d101539ce6342ce95fc3bf13cb2ecfc_515a64b6-1b61-45b3-bfda-7175a9aa8848.jpg?v=1778657639","url":"https:\/\/www.powersportsuperstore.com\/products\/namura-technologies-nx-40025-piston-kit-standard-bore-66-35mm-10-9-1-compression","provider":"Powersport Superstore","version":"1.0","type":"link"}
