a buddy of mine drives a Honda CB500 and pays 150 $/year for liability
but that's German prices (higher than in the US, normally)
btw I'd take a Honda, Kawasaki or Yamaha instead of a Suzuki. No offense, Amanda, but IMO Suzukis suck. They are cheap, but they don't have the best performance/price ratio...
on the other hand a Suzi or a Honda are great for starters...
can you post some pics of the bike?
btw I wouldn't start with a 750ccm class bike...that's seriously too much power. Go 500 or sth like that... 750 can be really dangerous
