It should fit, it will have a slightly different gearing ratio though

[honda4h]

gearing ratio is no big deal. just needing to know if there compatible if not i need to order the proper one. it takes over a week to get to me buy mail. thanks for the info

No problem. Looking at a trx125 next to an atc125m there isn't much difference. 4 wheels and a plastic seat pan is about all the difference between the two.

it's in the sub tranny trx has totally different setup with reverse. and no hi-low range. i have had the to apart before but never messed with the sprocket

Your right totally forgot about the reverse on the trx. They were so much heavier than the 125m. The atc didn't need reverse because it was so much lighter. When I bought mine it was on all flats and after trying to roll it unsuccessfully I got pi$$ed picked it up and just threw it in the back of my trailer. Landed upright like a 3 legged cat. :beer
