Yz 250 piston specs vs tri-z250

[NEWDUCK]

Since I have torn down my tri-z I called wiseco and asked them where the piston came from because the tri-z piston numbers they had didnt match my numbers. The piston is for a yz 250 83-87. I asked them what the diffrence was and the wrist pin sits .015 higher and the top of the dome is .055 higher than a tri-z piston. So just incase any body was wondering the diffrence between the two if any there you go.

The Wiseco pro-lite is lighter then the Pro-X ( by a decent amount). Cant remember exactly how much, but Ive measured it before................
