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 A piston is 101.97mm Made in Taiwan Fits 2006 Yamaha Raptor 700 YFM700R 2007 Yamaha Raptor 700 YFM700R 2008 Yamaha Raptor 700 YFM700R 2009 Yamaha Raptor 700 YFM700R 2010 Yamaha Raptor 700 Special Edition YFM700RSE 2011 Yamaha Raptor 700 YFM700R 2012 Yamaha Raptor 700 YFM700R 2013 Yamaha Raptor 700 YFM700R 2014 Yamaha Raptor 700 YFM700R
