Sorry to hear about your bike being totaled. Pretty heartbreaking
I agree with buying the bike back and seeing how you can salvage it. No matter how riders look at it we are involved in a risk related sport and sometimes "stuff" happens. Get more experience riding a 250 or equivilant, buying a cbr 600rr would be an unwise move. That is a powerful bike and less forgiving. It is awesome that you have not given up and still want to ride, good for you. Wish you the best
