USAA doesn't write motorcycle policies anymore, they pawn it off to Progressive, they only write car policies now.
Personally, I'd get liability and forget it. It may sound bad, but if you have an accident bad enough to have to file a claim, odds are you won't be alive to be the one to file it. It also helps if you're covered w/ some form of health insurance for minor injuries (broken bones, road rash), but as far as the bike, usually they are total losses.
By no means am I suggesting not to get one, I'm a rider (05 Yamaha R1) and I love it, I'm just saying lets be real, on a rocket, you're living life on the edge. You're either gonna fall off the edge or you're gonna continue to make it.
Oh yea, I would recommend theft coverage and uninsured motorist which you should be able to add to a liability policy.
Wrong!!! Low speed accidents can thoroughly fuck you up without killing you!
