I'll have to test fit the pipe before going any further. Thought the 250r pipe hung down a little to the right of the frame rail.
I found some nice yfz450r nerfs with heel guards that look awesome and have a 22" spacing. Worst case they will work with a little tweaking.
Hontrx265r, have you seen a new LSR propeg frame with that spread recently?
Btw250, thats a chinese knock off "Acerbis" chain guide for. Pit bike I bought off Alibaba for 7$ and modified to fit on the 250r.
