well many things from those engines are the same. The best thing to do is go to ktmworld.com or ktmcyclehutt.com and cross reference the parts. I only say that is because the 125sx is a 6 speed and the 200exc is a 5 speed. I do know for a fact they are the same cases so the trany will interchange but do your home work . go to those sits go through the parts manuals you will like what you find ! I did! TAKE YOUR TIME !!! you don't want to take the engine apart once you put it back together its not fun !
p.s. great bikes easy to work on very forgiving but
DO YOUR HOME WORK TAKE YOUR TIME!!!!!!!!
