If in doubt , get the trusted one from EBC UK , they make discs for hyosung. If in doubt, ask the local bike shop as they will usually have a trade account to get EBC pads, so ask them to get you locally an EBC disc for Hyosung GT, if its urgent for MOT etc. I usually have discs on ebay but used though with life in them, that’s a little cheaper than me ordering a new one for a client quickly.
125, 250, 650 = GT and GTR = Same discs. Up to 2019.
