Manufactured by Namura Kit includes piston, rings, pin, clips, top end gasket kit you get the exact item pictured The HyperDryve line of pistons is composed of a space-age hypereutectic aluminum alloy developed by NASA. Engineered to maintain its high tensile strength up to 700 F 370 C , 50% higher than a conventional cast piston, this gives HyperDryve pistons the strength to perform under operating conditions normally reserved for forged pistons. Cast piston has super-high silicone content for additional strength Piston skirts are Molybdenium Teflon coated to minimize resistance/wear and provide extended life Piston dome is anodized for superior heat resistance and longer lifespan Namura gaskets use performance materials to increase durability and provide greater reliability Kit is for standard bore size 102.00mm Size C piston is 101.99mm Made in Taiwan Fits 2008 Yamaha Rhino 700 YXR700F 2009 Yamaha Rhino 700 YXR700F 2011 Yamaha Rhino 700 YXR700F 2012 Yamaha Rhino 700 YXR700F 2013 Yamaha Rhino 700 YXR700F
