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 PistonsĀ , because all hyosung calipers suffer from piston corrosion and seizures.
- Stainless PinsĀ (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 ,Ā 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.Ā 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 5/8Ā (from St7, GV650, GT650 that fit 22mm bars as some cruisers have 1 inch bars!)
If your master cylinder says 5/8 = keep it.Ā 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-EFiĀ Ā (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!
