Seized front brake calipers; can’t ride; missing all the good weather; F*#*!
Is there a CHOICE of FRONT BRAKE CALIPERS that fit perfectly on a 2008 Carby model Hyosung GT250R?
I think the GV250’s won’t fit as the Bracket is different.
I’d like some calipers off a GT650R but i’m not sure they are a DIRECT SWAP. I don’t want to do any more work.
What brake calipers are the BEST for someone who really needs excellent stopping power? … (of which i haven’t experienced on this bike yet).
What are all the options of BOLT-ON brake Calipers for the 2008 GT250R?

The caliper is used on the 650cc, that should tell you that it’s more than sufficient for a 250cc motor and you have 2 discs also which is a luxury as most 250cc bikes only have a single sided caliper and disc x1.
So improving it would require these:
- Braided Goodridge UK/Hel lines, you want a proper motorsport brake line.
- Stainless Pistons , because all hyosung calipers suffer from piston corrosion and seizures.
- Stainless Pins (that your brake pads slide one)
- SOme good grease behind each pad and on the PINS
There, you almost do not have to worry about that caliper for a very long time , anbd also all you are doing is cleaning the caliper during brake pad changes.
GV250 uses the same caliper , just remove the bracket and use your own bracket.
GT650 , they got upgraded to the BIG 4 piston calipers (kawasaki look alike type of calipers) , but the forks also got updated. They will not fit 250cc without the updated 650cc forks.
Other brands = Not known, I doubt it!
If fitting other brands / makes == Fabricate a metal plate mount to affix the caliper to your forks and possibly master cylinder upgrade to 5/8 (from St7, GV650, GT650 that fit 22mm bars as some cruisers have 1 inch bars!)
If your master cylinder says 5/8 = keep it. It’s as good as it gets and it’s very good.
You could still get 650cc calipers but must be identical yours (silver TCTC Korea brand), that’s pre-EFi (around 2005-2008)
Be a good idea to go stainless on your rear caliper on its pistons & pins as here in UK, we get rear brakes failing more than the front!

Good information, thank you Marcel. You saved me a lot of exp[erimentation & time/money wasting. I saw the GV250’s looks same – glad i can swap bracket. I wanted to try the new black GT650 EFI brake calipers – but i had a feeling they wouldn’t fit. Thank you – save me money & time. You are right about corroding Hyosung pistons. All my pistons front & rear are seized. I pulled the front apart got them moving but they locked up agaoin as soon a s i put them on the bike. My Front Master Cylinder also seized after i took it off for a week to try out another one. I had to buy another form Hyosung and i will be buying the brakes form them too. Found 2nd-hand Hyosung calipers but they ask too much & they will be seized & rubbish anyway.
I went for ride with NO front brakes … i wouldn’t recommend it to anyone who wants to live. Your heart makes you pull the front brake lever, even when your brain knows it won’t help ya at all. Anyway, i’m still here. I’m like the back-brake expert now. The trick is to put your left foot on the road to slow down like Fred Flintstone. Takes a bit longer than normal.

Marcel, just tried to buy FRONT CALIPERS from HYOSUNG. They say they only have REAR Calipers for GT250/650. This part looks the same as the FRONT but is it? Is the REAR caliper on a 2008 Hyosung GT250R the same as the 2x FRONT CALIPERS? I got to buy them soon so i can ride. Found it weird that Hyosung don’t offer any FRONT CALIPERS except the new black EFI ones.
FRONT CALIPER Part Numbers: 59300HG5112 (GV125 / GV250 ).
REAR CALIPER Part Number: 69300HN9102 69300HP9500 69300H79B00 (GT125/GT250/GT650).
I need 2x Front Calipers for GT250R 2008. There’s no stock of FRONT. Is the REAR the same exact part?

Which Hyosung is this ? Becareful some sites are very sketchy with no real association with KR Motors Korea (Real Hyosung) but they buy their own stuff and store in a shipping container yard!
anyway, if its SILVER and says “TCTC” on it , it is the same caliper used on front & rear for the GT250R before 2012
After 2012 = All GT250/650R used an EFi rear caliper which will NOT fit the front!
If you get a rear silver caliper that looks like yours, remove the mount , and use the front mount. As the rear mount is for the rear only.

Hey mate, thanks for helping – i have to buy them soon- need to ride. I’m NOT buying aftermarket calipers but they exist.
Hyosung say they have NO TCTC FRONT Calipers for 2008 Gt250R. But thy DO have REAR TCTC Calipers for 2008 GT250R.
Is that REAR Caliper made by TCTC for a 2008 GT250R exactly the same as the FRONT CALIPERS should be, for my 2008 bike?
They look the same. They have a different bracket, as you say. I can undo the 2x bolts and put my bracket on, as you say.
My choices are 2x TCTC GT250R REAR CALIPERS to be put on the FRONT of the bike.
Or, 2x TCTC GV250 FRONT CALIPERS to be put on the FRONT.
Are ALL these CALIPERS IDENTICAL? Identical apart from the brackets, which undo with 2x bolts?
Would you buy the Rear GT250R calipers or the Front GV250 calipers to put on the front of a GT250R?
Sorry to keep asking but Hyosung jsut sell parts – i don’t think the guy i talk to there can even ride a motorbike.
He has to contact KOREA everytime i ask a question. Product Knowledge is what it’s about, expecially if trying to sell it.

TCTC Silver = Identical (Every Hyosung before EFi era)
So yes, you can get rear GT250 calipers , remove the bracket , and put them on your front mounts no problem.
Just bleed nipples may face down or up! (TCTC is funny like that!)
GV250 Front Caliper = Same as GT250R front , just swap the mounts as GV uses different forks that’s all. The actual caliper is the same.
KR Motors doesn’t sell calipers on their own, they “have” to come with mounts , probably why he said “i only have rears” . As Hyosung Korea pre-fits the mounts at the factory as they make them after TCTC sends the calipers to them.
We can’t buy new mounts separately that’s why , they come with the calipers as a whole set.
No problem, least you have a spare rear mount!

Thanks heaps, Marcel. I’m getting the REAR Calipers for the front of my bike as we speak. I thought i’d check if you’d posted. Glad you say the rear is ok as i NEVER had a bike with the same SIZE calipers on the rear & it was hard to go for them. But i can use a bracket when i take them off & pop it on the rear for looks. 🙂
