Piston for a KDX 125
Hello all, I know that some of you have or know about the KDX 125, well mine is a 1991 or 1992 model and I think I had a lean seize on it and now I need to replace the piston as well as a bunch of other things on it. My issue where I need some help is figuring out what piston to use. Because of the lack of 125s in the US, I can't find the exact one on ebay although I can find a bunch of KX125 pistons. Current piston was not original and I don't have info on it. So my question is, what would you recommend that I use?
As a side note, is there some way to tell for sure what year this bike is?
Thanks!!

I would try contacting the various piston manufacturers and see what they say. I'm sure at least one of them made pistons for it at one time.

Awesome thanks for finding that, but WOW that's more than I can spend on the piston. With international shipping to me I'd be looking around $150!! Too much for a 20 yr old bike that is worth $750, at least that's what my wife is going to say.
That's why I've been looking at KX pistons, I'm just not sure it'll fit/work correctly. Like the skirt, ring gap and stuff.
What do you guys think? Any other 125s out there? I can't be the first to try this.

I've been comparing numbers on these diagrams and it looks like the only difference is that the KX only uses one piston ring versus the KDX 2 rings. The connecting rod and pin are the same.

What's the difference with using a piston with just one ring?

They used 1 ring on the kx for faster revving. They also wear faster with just 1 ring....but like slick nick said, don't assume they're the same by looking at a picture. Exact diameter, height, piston skirt shape, wrist pin bearing size, oil holes, etc. all need to be factored in.Mfkdx wrote:I've been comparing numbers on these diagrams and it looks like the only difference is that the KX only uses one piston ring versus the KDX 2 rings.

Even though they use the same wrist pin it might be located farther from the crown or closer to the crown. In either of those situations you might have a serious problem, even though it appears to fit otherwise.
