250x, 300ex???
The 250x and the 300ex frames are identical. . .the only difference in the entire bike is the bigger bore which makes the motor into the 300. I put an atc 350x motor in my 250x frmae with minor modifications. But the 300 should slide right in. . no problems. Good luck! Let me know if you have any questions.
