Can anyone positively ID these forks. I think they are IT175 - 36mm.

Without length measurements I am guessing YZ125D/E, IT175F and various DT125's & 175's. If they are original then they are probably IT175F but many parts are interchangable so if the original ones were rooted then YZ125D/E would bolt straight in but had air caps but may have been replaced.

i think the DT125/175s have 32mm stauntions. so i'd count them out if yours are 36mm.

Length 925mm extended and 725 compressed, approximate (within about 5mm) allowing for aftermarket caps.

From what I can make out, by appearance they could be E,F,G,or H. I'm assuming they have 200mm of travel. Does that help anyone to ID?

I am quite certain they are 79-81 TT 500 or 80-81 XT 500, with Goki air caps.

The Goki air caps is right but I don't think they're XT or TT because of the Headlight Holders which I believe are original.

Im not sure exact years but those forks were the same as on IT and TT/XT for a few years anyway. I think the XT headlight brackets were rubber mounted? did the early IT's have brackets like that?. just have to wait and see until a knowledgeable 500 owner such as CJ drops in. Ignoring the brackets i still think they are late model XT/TT

NOT YZ125D/E. The web above the axle is too short.

Fork boots suggest IT175G.

I would have thought the 'ears', and many other bits, would be common to all IT's. What size forks were the 400's? 36mm?

I think I found the answer, at approximately 200mm of travel, its probably off an 'f' (195mm). Whatcha reckon!!

Yes, but not all of the same style. IT175D/E had a lot less ribs - not sure about 175F, but I thought they were like 175D/E.
