kx125 cylider options

Check the diagrams online and if different year models use the same head and base gasket theyll usually interchange. On the kx250 a ton of cylinders interchange but each uses differing power valve parts to some degree. Im not sure of the 125's though.

Or have a sleeve installed if youre just a trail rider like me. Everyone here will tell you not to sleeve, but it sure is nice to pay a local shop $30 to bore it when it needs it rather than $259 for a coating that takes two weeks to perform. Just my opinion.
