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
Will this fit a stock cylinder on a 2006 crf250x
By Ty
Yes, if you were to select the 2006 Honda CRF250X 4-Stroke piston kit from our fit guide, you'd receive the correct piston kit to fit your machine. The OEM bore is actually 78mm, which is well within spec for this 77.96mm piston to fit without issue.
Does this fit yz 125 06 modell?
By Daniel
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.
I have a stock jug will this be the same size piston as stock for a 2015 rzr 1000
By Bill
Yes, the kit offered for that 2015 RZR 1000 XP would have the stock size 92.95mm pistons included.
Does this come with everything? And will this fit perfect on stock bottom end of 02 yz85 with no problem?
By Jermelle L.
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.
Does the 1999 cr125 top end kit come with a needle bearing?
By Anon.
Yes, the needle bearing would be included with the piston kit for the 1999 CR125.
Would I need fo buy a additional gasket kit for the rebuild? 2017ktm250xc
By 2017ktm250xc
This kit should have all the gaskets you need to remove/install the top end of your machine.
2012 KTM 350EXc-F piston is 12.1 correct? this listing states 13-1 ,would it work without race fuel?
By Anon.
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.
