Being a universal saddlebag support it not designed for any specific bike. It does come with varying sizes of bolts and spacers to make it compatible with many different bikes. The problem with your VT500C is that there are no mounting holes for this type of support in the fender side rails. For proper fitment, you would need to drill holes and utilize nuts on the backside of the rail for these to work. They can work but it will not be a direct bolt on.
