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\u003e1992-1998 Yamaha YFB250 Timberwolf 2x4\u003cbr\u003e 1994-2000 Yamaha YFB250FW Timberwolf 4x4\u003cbr\u003e 1999-2004 Yamaha YFM250 Bear Tracker","brand":"Namura Technologies","offers":[{"title":"Default Title","offer_id":44003409100922,"sku":"4914443","price":73.1,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0004\/3312\/7455\/files\/8d101539ce6342ce95fc3bf13cb2ecfc_dd4d372a-b394-420e-ad28-9bba44c2542e.jpg?v=1764259991","url":"https:\/\/www.powersportsuperstore.com\/products\/namura-technologies-na-40015-2-piston-kit-0-50mm-oversize-to-71-45mm-8-7-1-compression","provider":"Powersport Superstore","version":"1.0","type":"link"}
