Details

    The Cometic Top End Gasket Kit comes with everything you need to properly complete a total top end rebuild of your engine. Cometic manufactures their gaskets to exceed OEM quality from chemical resistant, non-asbestos, flexible aramid fiber that is laminated on top of a stainless steel core. This makes for thick, exceedingly robust gaskets that won’t fold or tear during installation, giving your top end the tight seals it needs to keep running strong no matter the speed.

    Specs:
  • Complete top end gasket kits with head and base gaskets
  • Laminated aramid fiber construction
  • Gasket material is laminated on top of stainless steel cores
  • Aramid fiber contains no asbestos
  • Gaskets are flexible and won’t tear
  • Aramid fiber resists chemicals including fuel, coolant, and oils

Great kit
The only thing the kit didn't include was the o-rings for the power valve axles, but technically for doing a top end you don't need to remove those anyway.

Hopefully just one bad experience.
I hate leaving bad reviews but in this case I must. I bought this kit for my 2017 KTM 450. I installed both gaskets with a clean mounting surface and torqued my bolts to spec only to have both seap oil down the side of the top end upon my first ride thereafter. Purchased another top end gasket kit (different manufacturer) and had good results.

Needed top end gaskets
Cometic is the best there is. Sure you can get the cheap paper gaskets for less money, but I'd rather have the peace of mind that they'll last

Complete Top End Kit
Kits are specific to your model machine. Had everything for my KTM 520 including valve stem seals, exhaust gasket, O rings, crush washers. Time will tell on durability, but am happy with the quality.

Good kit
I used this kit when rebuilding my 2004 KTM 300. I have put lots of hours on after the rebuild and have had no issues with the gaskets, I would buy again.

I chose these because of their construction and quality. worth the extra cost for the quality. the brunt of the kit fits great... intake gasket looks to be for a kx80... guessing its a miss pack, reached out already and we will see how it gets resolved...
