U better check again! 2 strokes oem pistons are made by vertex but NOT 4 strokes. Cp makes all new 4 stroke pistons and are oem because vertex isn't high enough quality

When I owned my 350sxf I was told by a well known engine builder that he only uses OEM or CP in KTM's.

And that every wiseco he tried in a 4 stroke KTM lost power.

Vertex made KTM 4 stroke pistons for years. My 350 had "Vertex" right on the OEM piston. I am pretty sure they know how to pull it off.

I built my engine with a wiseco. I made more power.

I know they do not make them anymore. I was just stating that Vertex made them for years with no issues. You are making the ridiculous claim that a company who has been providing pistons for years, magically can not pull it off.

How many hours were on it when you refreshed it? Same compression between the stock and wiseco? You dyno'd it before and after rebuilding it in the same day? Because weather conditions affect things a pretty good bit. Not doubting you just asking.

This guy builds tons of these things and does a lot of testing. I was just relaying what he told me he had found.

Wiseco has a couple new versions of 4 stroke race pistons out now that seem to be better than what they used to make. And of course their 2 stroke stuff has always been good.

Alright smarty pants your so fucking smart why doesn't ktm use vertex in the 4 stroke anymore? They hold up so good why they switch to a more expensive piston? Vertex refused to meet the quality standards for ktm, I'm not a dumbass behind a screen throwing out bullshit that I'm not informed on, like some people. Since your apparently too lazy to do any research yourself I'll find it for u or call ktm yourself so u can be better informed so you don't sound so stupid!

Nope fair bit more compression, bowls shaped. Plenty fast now..
Only dyno was the uphill long start where I pulled away from two other bikes that'll dyno more everyday of the week than a 15 Honda 450. Nice feeling when you do all the work yourself.
The Racers Choice is a nice piston design. Can't comment on the standard ones.

Yep sure am wanker. When you're neck and neck with two others and grab 4th and walk away I'd say that's dyno enough for me.

No shit the higher compression piston makes more power than a stock one.

KTM will use whoever fits the contract to make their OEM stuff, Vertex was has been a supplier and also Wossner, Its also plausible to think that Pankl is the current supplier for OEM pistons/rods with the four stroke stuff seeing as they sponsor both the KTM and Husky factory teams in the GP's and the US.

You can not go wrong with Vertex, Wossner, Pro X & Wiseco. Steer clear of the imitators, measure your bore properly and order the correct size, measure and adjust ring end gaps to suit, drill exhaust bridge lubrication holes where necessary and you will have no problems.

Also worth noting is that CP Carrillo do not make two stroke pistons... they are a Four stroke only company so is Pankl. Pankl also name CP Carrillo as a partner in their company structure, also it is not outside of KTM/Husky's history to have one company supply the 2T pistons and another supply the 4T stuff.

Id be willing to bet it had way more to do with a supplier/volume/price type thing than a quality thing

Before you try an insult a persons intelligence, you should probably go back to 3rd grade and learn how to use "your and you're." No one will ever take you seriously when you communicate at an elementary school level.

This is quoted from a thread on here. "KTM owns Pankl. CP Carrillo is a sub company of Pankl. I think it was January 2016 that Pankl went from 70% owners of CP to 100%." So it looks like it was nothing to do with quality, just purely from a business standpoint. Smarty pants.
