Namura’s Complete Gasket Kits are designed and produced using high quality materials to help withstand the needs of today’s engines. Gaskets are designed to OE specifications with performance materials to provide greater reliability and durability. Whenever possible we use picture of the actual part number. Gaskets are manufactured from materials specifically chosen for each individual application. Namura gaskets are manufactured to OE-specs, which means no trimming or fitment issues. Materials are explicitly selected for their temperature, oil, fuel, and coolant-resistant qualities. The seal between your cylinder and cylinder head is constructed from multiple layers of stainless steel to resist corrosion and erosive chemicals commonly found in your engine. Gaskets are coated/embossed with a Fluoroelastomer based rubber to tightly seal the metallic mating surfaces. 2017 KTM 450 EXC F Six Days. 2017 KTM 450 EXC F. 2018 KTM 450 EXC F. 2019 KTM 450 EXC F.
