What probably really hurt the 87 atc125m sells also was they made a trx125 also with the same motor. Kind of a shame they were cool looking trikes.Originally Posted by aldochina

Anyone know where I can buy a 125 fairing?

New guy here, this thread seems to be pretty deep, but I'll ask anyway. I got an 85 125m in very rough cosmetic shape, but great mechanical. Electrical has issues. SOOOO, one post up mentioned trx125 and that opens up the question for me. Will the rear fender and seat off a 1986 trx125 fit on my 1985 atc125m well? I'm ready for bolt hole locations being slightly different. Thanks for the help. George

Is the bottom end/crankcase the same on an ATC 125m as the trx125? Will the side covers bolt holes and such match up. I have a re-bored top end from an atc125m that I'd like to put on the bottom end of a trx125 but the left side cover is missing. I have the complete engine of the 125m but something is messed up in the gears and don't feel like tearing into it.

The bottom ends are different(think the clutch cover is the same though), at least for the first generation 84/85 Atc125m's and 85/86 Trx125's. I have both an 84 and 85 Atc125m; the engine stuff is basically the same except the 84 is a 4 speed (all down), the 85 is a 4 speed (all up). Also the 85 Atc electrical system produces more power. I'm pretty sure the top ends on the first gen Atc's/Trx's are the same.
Also, there's a good chance that your Atc has either a broken shift drum stopper arm, or a bent/broken shift shaft fork. These are two very common problems on the smaller displacement Honda Atc's/Atv's /Motorcycles. It isn't hard or expensive to fix these issues either. Of coarse you could have some other kind of issue going on, but chances are it's one of the two things I mentioned.... Was your Atc missing shifts and or slipping out of gear? If so, I would take your clutch cover off and check out the shift drum stopper arm and shift shaft fork.
I'll try to post some pics for you.

Here's some pictures.
First pic I found on the internet: Shift drum stopper arm on left, shift shaft fork on the right.
Next pics are from me when I replaced my shift drum stopper arm.
