2008 KTM 450EXC-R Dirt Bike Top End Engine Gasket Kit [For 97mm Bore Size]

Cometic Top End Gasket Kits

Cometic MLS (multi-layer-steel) Head Gaskets are ideal for any combination of head and cylinder materials. MLS Head Gaskets are comprised of two embossed viton coated stainless steel outer layers and a variable stainless center layer. The variable center layer allows us to create multiple gasket thickness options. No re-torque is required after initial torque set.

Rubber coated single layer steel base gaskets are viton rubber coated with a steel core and in some instances embossed.

Cometic AFM material engine cover gaskets are made from a chemically blown compounded nitrile synthetic rubber that is bonded to an aluminum core. AFM material has a temperature resistance of over 250° F (121° C) and an 85% recovery while maintaining a strong torque retention. Gaskets made from AFM install dry and do not require a re-torque. Typical gaskets made from AFM include: cam chain gaskets, timing cover gaskets and water pump gaskets.

Viton valve stem seals are made from hi-temperature Flouroviton with Teflon to prolong valve stem life and have a spring on the wiper to maintain a positive seal.

Exhaust gaskets are made out of various materials, as required by model, such as armor clad, copper, graphite or spiral wound steel.

Copper washers and Viton o-rings are used to seal drain plugs and engine covers with stock o-ring seals.
