Is there any upgraded forks to put on the gs500? Mine are bent and need to put on new ones anyways.
37mm are their size and there are no after markets avail. You can swap the entire front enf with something like a Katana thats a 41mm.
In the meantime, here are some forks for sale

GS500 forks are fine if you put in better springs.
if you are racing, good springs + emulators make the front end quite OK
For the street just new springs matched to your weight are OK
Hmm....I took it as wanting something stronger structurally versus better suspension
Start with springs and oil. Consider emulators and a brace. A full front end swap is a huge pain on a street bike. Benefit over upgraded internals isn't worth the cost unless you're racing.
