not quite. apart from the usual change in tanki and tappa stickers, ur cg125 has smaller front brakes. the new ones have bigger front brakes. i am not sure, but i think from 2007 cg125 started having a bigger front brake.
Also another thing that was also different was the handle bars. I think from 2007 cg125 had different handle bars from cd70 (before both used same handle bars). if u look at older models their handle bars are a little bigger/longer in height than the current models. the cd70 still have the same handle bars. but now cg125 from 2007 have smaller (in height) handle bars. so that is another change. and of course from 2010 the buttons were all placed on the left hand side of the handle bar. and also the clutch and front brake cables had a little black rubber over them.
