IT250J.
DT175N (late type, has been cracked and repaired).
IT175G.
YZ125N.
IT465 (has been MX-ified a bit, with the rear loop cut off, etc).
YZ250C (has engine mounts cut off).
I also have swing-arms for all of them except the IT175 and YZ250C.
Cheap. Or will swap for any model twinshock DT or MX frame.
