When you contact the city - Tell them you were doing the speed limit.
If you had died from that your family could have sued them for a lot more the what it is going to cost them for your repairs.
They might even have a form for you to fill out. Do it ASAP. If you can get pictures of the hole all the better.
Also get it to a dealer and have them quote the repairs and have that with you when you go in, if you can.
How did you get the bike home???
Sometime injuries don't show up for a day or two after an impact like that. Keep a sharp eye out for any pains you may experience in the next few days.
Good luck - Take action to get the results you want. :tantrum:
