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\u003e1983-1985 Yamaha PW80\u003cbr\u003e 1991-2006 Yamaha PW80","brand":"Namura Technologies","offers":[{"title":"Default Title","offer_id":44004145037434,"sku":"4914780","price":50.29,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/8d101539ce6342ce95fc3bf13cb2ecfc_54ce0451-9d11-4e24-aff8-7cf3d1293daf.jpg?v=1764261796","url":"https:\/\/www.powersportsuperstore.com\/products\/namura-technologies-nx-40008-piston-kit-standard-bore-46-97mm-6-6-1-compression","provider":"Powersport Superstore","version":"1.0","type":"link"}
