Hi mate,im a nooby but i have a rd125lc mk3 uk model which is 2hk,and also have a mk2 rd125 that is 1gm,so it sounds like its a uk mk3 frame with a mk2 engine in it.
but the guys will let us know if thats correct.

As above sounds like a MK3 frame witha MK2 engine fitted . does the barrel have a powervalve fitted . Im asooming is does not . having said that you can put a MK3 barrel on a MK2 bottom end if you fit a MK3 conrod.

good thinking when you have it apart may as well do everything new so you can breath eazy knowing it all new when you start riding .
