Great Piston, the only brand I trust to fit perfect every time.
Vertex Pistons are the best pistons, from what I understand they are the ones that KTM uses in their bikes or so I’ve been told. My only recommendation is that you purchase the easy circlips from Slavens racing because the circlips that come with the vertex piston are the most difficult I’ve ever had to install. Other than that it’s a great piston with great quality.

This kit is great for KTM
This kit seems to be working very well in my KTM. I had a fear of not installing the clips correctly, and purchased different ones.

Ranger pistons
Ive put these in 3 ranger 800's and they work great, one of them had a slight knock and I cheated, honed the cylinder and put these in. Runs like a sewing machine!!

I'm in search of the "d" size piston kit by vertex, can I find it here?
cody w on Oct 27, 2016
BEST ANSWER: Nearly all of the Vertex pistons we carry are either "A" or "B" sized pistons. But if you can provide the machine you're purchasing for, I'll check to see if we may have the "D" piston.
when should I replace the top end on my 2013 ktm 150 xc. I am a amatuer trail rider and have 55 hours on the engine? Thanks for any advice and knowledge concerning this question.
Jon S on Nov 10, 2016
BEST ANSWER: AT 55 hours you are most likely due. You may need to look into honing the cylinder also. I highly recommend the vertex piston. Nicely machined piston
Does it come with everything or will i have to buy something's separate?
A shopper on Dec 17, 2016
BEST ANSWER: You will need a wrist pin bearing and top end gasket kit
Cometic Top End Gasket Set

Wiseco Piston Wristpin Bearing
Does this kit come with wrist pin bearing?
roger m on Sep 7, 2016
BEST ANSWER: Roger, you will have to purchase the bearing separately. It comes with piston, piston ring, wrist pin and circlips.
Is this the "B" piston or equal to KTM Group 2 Piston? KTM recommends Group 2 or "B" piston for bikes with over 50 hours on them
MONTY C on Aug 22, 2016
BEST ANSWER: Yes, this is the "B" piston and would work for your application.
Will this still fit if ive had my cylinder honed? Ktm 350sxf 2014
kieran b on Feb 28, 2017
BEST ANSWER: Honed cylinders should be the same size as before,boring a cylinder is what changes piston diameter. Be careful when honing a plated cylinder as you just want to remove the glaze on the cylinder wall ,DO NOT DAMAGE THE NICKEL COATING. A simple cleanup can be accomplished by rolling up some magazines with a full piece of wet/dry sandpaper (use wet) 400 grit .just make a few gentle ,rotational passes thru the bore .Make sure you clean up all residue .Rocky MT has a nice nylon honing brush also. The plating in your cylinder is critical and expensive to replace, so be gentle.
Is the standard vertex piston forged or cast?
Eric B on May 5, 2017
BEST ANSWER: From what I have read,all 2 stroke pistons are cast.Some 4 strokes,depending on application, is either cast or froged.Cast for lower rpm 4 strokes and forged for high rpm 4 stroke applications.
On my Yamaha warrior 350 the Piston looks shorter than the one in the picture is this going to be a problem?
Carter W on Jul 28, 2017
BEST ANSWER: This picture is generic and doesn't necessarily represent the actual product you will receive. If your machine is listed in the drop down menu, it will fit.
Does this standard vertex piston for the 2005 kx 125 have 1 or 2 rings?
Jason K on Apr 5, 2017
BEST ANSWER: Pretty sure it was two mate, although it was a long time ago now and I have done a few on other bikes since. Don't remember doing one with only one ring though.
I had the head modded don my '15 KTM 200 and the company said to buy a piston with a zero deck height. Any ideas what that means and does Rocky have it???
A shopper on Sep 28, 2017
BEST ANSWER: Unfortunately we will only carry the stock sizing pistons for that machine. You may be able to go to vertex themselves though.
Oem piston for my bike is 54mm. Why is this and others smaller?
michael a on Sep 6, 2017
BEST ANSWER: Not all pistons are made of the same materials or process(cast vs forged) and thermally expand at different rates But they all fit the same size bore when they warm up and expand.
what should the compression be reading on a 2013 KTM 150 XC? I am having trouble locating this info without a owners manual.
Jon S on Mar 7, 2017
BEST ANSWER: Compression readings are variable based on the tool being used, the method used, and the various tolerances of the top end parts. If you could find a reference it would be a range like 130-160 psi so it isn't all that much help. The best thing to do is to take a compression reading when you rebuild the top end using your own tools and method that you can repeat so you have a baseline for checking the health of your top end. The best reading will be when the engine is at operating temperature and after there are a couple hours on a new piston and rings. It gives them time to seat. There are plenty of youtube videos to help.
the piston that came out of my bike is size B the one i ordered is size A will this work in my bike?
A shopper on Feb 22, 2017
BEST ANSWER: I recommend you refer to your service manual for proper piston specs based on the wear of your cylinder. An "A" size piston is generally for new cylinders and a "B" is for slightly worn cylinders or a first rebuild.
Is this a single ring piston?
Logan H on Feb 4, 2017
BEST ANSWER: Vertex pistons match OEM specs.
Need a piston for 2003 kx 125. Each brand is showing different sizes for standard. This one is 53.xx others are 54mm even.
How do I know which one I need?
michael a on Dec 18, 2016
BEST ANSWER: Any of the pistons listed for your bike will work. When installed, the ring gap you set with the rings will make sure that the piston will seal correctly.
Does vertex make a wrist pin bearing or will Oem work with this piston? Thanks
DENNIS B on Nov 20, 2016
BEST ANSWER: I do not show that Vertex makes a wrist pin bearing. The OEM bearing will work.
