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\u003e1989-2004 Yamaha YFA-1 Breeze125\u003cbr\u003e 2004-2013 Yamaha YFM125 Grizzly","brand":"Namura Technologies","offers":[{"title":"Default Title","offer_id":44137820094586,"sku":"5464964","price":76.74,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/9e941bc33aa56bc7840b09dbdddfccef_c2531966-de26-451b-ab95-fc8fd72f1eca.jpg?v=1781407983","url":"https:\/\/www.powersportsuperstore.com\/products\/namura-technologies-na-40019-2-piston-kit-0-50mm-oversize-to-49-50mm-9-0-1-compression","provider":"Powersport Superstore","version":"1.0","type":"link"}
