Swing arm ID from XL250

[CRAPTECH]

I found this old xL250 1974 , and it had this swing arm on it, never seen one like this before, but with a little work may be able to but it on my old TM400. It is "I" beam type, and very light. anyone know who made it.
thanks Tgreen.

Checked out the video. That looks like a nice piece.

There was not a big aftermarket for '74 XL250 suspension parts, so it's very possible that someone adapted that from a late 1970's MX bike.

To me, the construction and shock placement is like something you would see from FMF, DG, or one of the other makers that made swingarms for '76 - '80 RMs and CRs. There were several companies that sold swingarms back then, like LOP.

FWIW, shops doing hop up parts for the XLs included Long Beach Honda and Al Baker, so maybe it is one of theirs.

I thought it was cool looking, may be cast. i have always wanted an XL250 MX bike, i may start another project. but if i dont use it i will sell it to someone that can. need bearings, might be hard to find. thanks tgreen
