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\u003e2000-2004 Yamaha YFM400 Big Bear 2x4\u003cbr\u003e 2000-2006 Yamaha YFM400 Big Bear 4x4\u003cbr\u003e 2007-2012 Yamaha YFM400 Big Bear IRS 4x4\u003cbr\u003e 1993-1999 Yamaha YFM400F Kodiak 4x4","brand":"Namura Technologies","offers":[{"title":"Default Title","offer_id":44108061900922,"sku":"4914412","price":84.06,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/8d101539ce6342ce95fc3bf13cb2ecfc_d7b66b78-4b31-47e9-9a11-d1dce1072511.jpg?v=1774077721","url":"https:\/\/www.powersportsuperstore.com\/products\/namura-technologies-na-40006-2-piston-kit-0-50mm-oversize-to-83-50mm-8-6-1-compression","provider":"Powersport Superstore","version":"1.0","type":"link"}
