@r1 bro gto,rx fork inner tube diameter is 30mm and i think cg,s inner tube is 28mm
thats why T will be replace. or if u can over bore(2mm) cg,s T from inside then n same original T u can also put gto,s fork, but make it sure k T over bre honay ki wjha se thin na hojay........mean if there is much place for over boring the T holes then do it,
doing this you will feel much easy, coz if you put gto,s T then lil issue of race ball fitting will must appear.......
