Is a 1985 HONDA TRX250 DIFFERENTIAL FINAL GEAR CASE and internals the same as a 85 250sx ??? I need to replace mine after finaly getting it apart. I found a trx250 one in good shape.My berrings and pinnion/ring are shot. Any advice would be great. You guys are the best !!!

i believe that they are...i know they look exactly the same

 

I currently have a honda trx250 86' model that i have mounted the motor off of a 250es big red. Been running fine all summer, no fab work whatsoever, lined up perfect so i can't verify the innards' but I do know this much, some trx250 parts are are easily swapped out for atc 250 parts.
