Very disappointing design and instructions
The first piston set came with only 1 oil scraper ring instead of the required 2. The 3 piece oil scraper ring setup is next to impossible to install correctly into the cylinder. The piston looks like a thing of beauty although it does not come with the cir-clip locating hole like the OEM piston does but did come with the "tangs" in the cir-clips that requires the holes to properly seat in the cir-clip groves. This 3 piece oil scraper ring set and cir-clip setup is a royal pain. The OEM KTM piston set may cost more but in my opinion a much better option in the long run. I've always had good luck with Vertex 2 stroke pistons but this replacement set for the 350 KTM 4 stroke has been very frustrating to get installed correctly (definitely not for the amateur home mechanic). Missing parts, incorrect parts - very frustrating.

Power house!
I just rebuild my yz 450f and noticed a night and day difference in power, going from stock to the vertex high compression piston. Alot more snap out of corners and all around power

I read a lot of reviews on this kit before I bought it and I am very glad I decided to purchase it!! It totally restored the power and it made my bike like new again! I would definitely recommend this to anyone! The kit was used on a 2008 yz450f

Noticeable power
Wanted to freshen up my sons kx250f during the off season. Vertex was recommended by my friend Tony @ REP Racing as an option to oem. Fairly straight forward install. Oil rings were a little tricky/delicate, not a big deal. When my son got on the track this season, he felt a considerable increase in power. Vertex puts out a very well machined, precision piston. Also KTM uses them as oem, so there’s that. I’ve had a good experience with their product, and will purchase from them again. Motosport awesome as usual.

A: I am guessing you are asking about gaskets and not seals. No. For this piston kit you would have to purchase a top end gasket kit separately.

Q: Whats the best aftermarket high compression piston for my KTM 350 SXF

A: Any of the aftermarket pistons are going to be good. I would have no problem recommending any of the major manufacturers such as, Wiseco, JE, CP or Vertex. Each engine builder will have his own preference, but realistically they are all pretty similar. Personally i have always used Wiseco Pistons in my bikes.
