Bore: 89.97mmCompression: 11.3:1 CompressionSizing: Standard BoreMOS2 (Teflon/Molybdenum) Coated Skirts - A rolled on application process provides a bond that is 10 times stronger than other spray on coatings. 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.This item fits the following vehicle applications:compatible with Arctic Cat DVX 400 2004-2008compatible with Kawasaki KFX400 2003-2006compatible with Kawasaki KLX400R 2003compatible with Suzuki DR-Z400 2000-2004compatible with Suzuki DR-Z400E 2000-2007compatible with Suzuki DR-Z400S 2011-2016compatible with Suzuki DR-Z400S 2000-2009compatible with Suzuki DR-Z400SM 2013-2016compatible with Suzuki DR-Z400SM 2005-2009compatible with Suzuki LT-Z400 QuadSport Z 2012-2014compatible with Suzuki LT-Z400 QuadSport Z 2003-2009compatible with Suzuki LT-Z400 QuadSport Z LE 2012
