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\u003e2021-2022 Gas Gas MC 50\u003cbr\u003e 2017-2021 Husqvarna TC50\u003cbr\u003e 2009-2021 KTM 50 SX","brand":"Namura Technologies","offers":[{"title":"Default Title","offer_id":44004143431802,"sku":"5454461","price":46.88,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/feaa987f252ad57530ff5a5fddb50bf8.jpg?v=1764261104","url":"https:\/\/www.powersportsuperstore.com\/products\/namura-technologies-nx-70020-b-piston-kit-standard-bore-39-47mm","provider":"Powersport Superstore","version":"1.0","type":"link"}
