The original post is vague...are you talking about a prefabricated hoop from the internet or did the guy actually have the hoop made/installed locally?
I paid $400 to a friends local machine shop to have my kz440:
1. rear hoop made/fabricated with a 20 degree kick up
2. aluminum seat pan made/fabricated with mounting hardware
3. frame chopped and cleaned up for rear hoop install
4. install of hoop and seat pan
5. guaranteed work=peace of mind
$400 was the friend price...$600 is what he would charge if not. Support your local craftsman...they are a dying breed!
