im 20, and i also have a 2006 gsxr600. state farm is giving me full coverage for $71/month. they class motorcycles by engine size, not supersport, super bike, ect..

my advise, get and keep full coverage. one day you might need it and its going to save your ass. my friend layed his 06 gsxr600 down 2 weeks after he bought it. it scratched the frame pretty good. he only had liability on it and he fixed the bike himself. downside, insurance would of wrote it of due to that deep scratch in the frame, and his resale value just went to SHIT.

also, like you said, theft is good to have. who knows man, what if you walk outside and see your bike laying on its side because someone hit and it left, or your kickstand digs into the asphalt.. a MILLION things can happen to a bike, and its usually when you still owe a shitload of money on it.

call around, im sure someone can give you a decent quote. hope i helped.
