Reply To: Rear Hyosung Shock by KR for GT250R
It is still made by Kayaba Japan , as they make all the forks and shocks for Hyosung (exclusively i believe, as I’ve not heard Hyosung use anyone else) though , it doesn’t shock me if Kayaba Japan used a china plant to make the updated shocks. It is weaker at the bottom yes. I would not try to undo the gold screw, may just be oil fill.
The spring adjustment (stiffness / softness) is on the 2x castle nuts resting on the spring itself. Further down makes the shock stiffer or further up make it very soft or very bouncy.
You can remove the bottom mount “U” shaped plate, that’s its only weakest point , otherwise rest of shock is OK. Get that duplicated buy someone else who does metal works and tell them to make the same “U” plate but 3x thicker & weld the nut for good.
