I HAVE AN 01 125 E\XC AND I NEED MORE FROM IT
CAN THE CYCLINDER - PISTON ETC BE PUT ON MY 125
FROM THE SAME YEAR 200 ?
WOULD IT BE A HUGE JOB TO TURN MY 125 INTO A 200
JETTING ? CARB CHANGE ? CONNECTING ROD ? PISTON ?

I had a 00' 125exc and thought it lacked too much bottom for me.
It would be easier and cheaper to sell it and buy a 200.
The carb is the same with slightly different jetting but you would need a pipe, cylinder, head, piston, probably a conn. rod, and maybe a crank.
With KTM prices this could add up to a bunch of $.
A 144cc big bore kit would be a option.

Secretly go to the dealer. Trade-in your 125 on a new 200, but swap the plastic. Don't tell your wife. She'll never know. :D

I have actually had a buddy do this, and guess what? It worked!
