Is buying a used Hyosung advisable?

I've been considering buying a bigger bike since a while now. Something in the 600cc class.
The Ninja and the Hyosung have caught my attention but honestly, I'm not that loaded. Hence, I've been dabbling with the thought of buying a used one.
I've always been skeptical when it came to buying anything second hand.
What are the risks of buying a used Hyosung? I've read that they aren't known for their solid build quality.
