Manufactured by Namura HyperDryve Series piston Kit includes piston, rings, pin, clips you get exactly what is 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 Kit is for standard bore size 102.00mm Size B piston is 101.98mm 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
