Up for sale is a used OEM engine cylinder with head and all power valve components installed for a 2002-2005 KTM two stroke 125 EXC, MXC, or SX. These parts came off a healthy 2003 KTM 125 SX. Everything is in excellent working condition. The cylinder wall still has decent cross hatching present. There are some minor, normal vertical scores from the piston skirt but no scratches, cracks, or gouges or any notable imperfections to the bore. The head has some some signs of detonation. Look closely at the pictures. What you see is what you get!
