[Sam]

Just had a friend give me a set of GT 650R front forks in perfect condition will these fit my 2009 GT125R  thanks for any replys

Yes , but if the forks use black calipers  , then get the 650 black calipers.

if they are old gen silver 650 forks, then sure you can use your own silver calipers already on it.

You can ask anyone around your area , that does metal fabrications, and a nice thick metal sheet,  cut to shape using your old calipers as template,  tap threads in to it, swap the caliper pins over , then bobs your uncle lol

Same principle applies if wanting to use genuine brembos ,  but get genuine brembos or 650 Hyosung master cylider as the 125cc resvoir and chinese ones do not have the strength to push big calipers.   Safety in brakes fella!

Ok Marcel I will look into that can I ask out of curiosity are the black 650 calipers a different size than my ones on my 125 sorry if the question sounds silly they just look so alike in images I have seen online

The 2003-2005 650 bikes and ALL 125 GT bikes use the same grey TCTC caliper until 2020  for 125  and up to 2005 ish for older big sister bikes.

The black ones do not say anything but are much much bigger and have 4 pistons inside.   The forks are black for a 650 with bigger spaced out gaps for mounting the bigger calipers directly

grey calipers use 2 pistons. and use a plate to mount to the 125 forks or grey old 650 forks  (floating caliper) , rather than bolted direct to the fork leg.

Hopefully i made sense ?

g’day Marcel, i have a 2012 GT650R with the black forks & 4 piston calipers.

have you ever tried to source internal fork parts for these?

i want to re-bush the forks but Hyosung do not list any service parts other than seals.

i believe the forks may be KYB.

Thank you Marcel for explaining that to me and yes you made sense lol
