Vertex kit

By   on  Verified Purchaser

Great kit! Everything needed for top end at a great price!


Everything fit great

By   on  Verified Purchaser

Everything fit great exactly as described for my 2020 KTM 150 SX.


So far so good

By   on  Verified Purchaser

Was recommended by my local KTM dealer. Everything we needed was there. Giving a 5 in quality for now but we don't even have an hour on the bike yet. So far so good.


Great product and kit

By   on  Verified Purchaser

Great product and kit, has everything you need. This is our second Vertex kit for a KX. Replaced the first kit after 100hrs on top end, piston and cylinder were still clean and had good compression for the hours at 140 psi cold. Son rides daily and races hare scrambles.

Questions & Answers

Ask Question

Does this fit yz 125 06 modell?

It says it will fit and the "Fitment Guaranteed" but if it does not fit on my stock yz 125, will i be able to return and get my money back?

Yes, looks like there is a stock size piston kit offered for that 2006 YZ125. Just be sure that you select the correct year/make/model and if possible inspect the engine before to ensure that you do indeed need a stock size piston.

By Andy
Answer Question

Does this come with everything needed to do a complete top end rebuild on a 2009 ktm 250 sx-f

Yes, this kit would come with all the correct components to rebuild the top end of the year/make/model you check out for.

By Andy
Answer Question

I have a stock jug will this be the same size piston as stock for a 2015 rzr 1000

Yes, the kit offered for that 2015 RZR 1000 XP would have the stock size 92.95mm pistons included.

By Andy
Answer Question

Does this come with everything? And will this fit perfect on stock bottom end of 02 yz85 with no problem?

The kit for the 2002 YZ85 would be stock style replacement kit with all gaskets needed for the top end, piston, rings, wrist pin, bearing, and clips.

By Andy
Answer Question

Does the 1999 cr125 top end kit come with a needle bearing?

Yes, the needle bearing would be included with the piston kit for the 1999 CR125.

By Andy
Answer Question

Would I need fo buy a additional gasket kit for the rebuild? 2017ktm250xc

This kit should have all the gaskets you need to remove/install the top end of your machine.

By Andy
Answer Question

2012 KTM 350EXc-F piston is 12.1 correct? this listing states 13-1 ,would it work without race fuel?

Yes, it would be a higher compression ratio than stock for that 2012 KTM 350 EXC-F. I believe you would be fine just running premium 93 octane fuel for that ratio.
