I'm sure that very high figure is for full coverage. There are a few things you might want to try first before giving up on motorcycling.
1. Shop around - Rates can vary VASTLY from company to company. Some companies don't want the hassle of insuring sportbikes, and their rates show it.
2. I would NOT go with the state minimums or a fly-by night company. Insurance is there for when you really need it. If you have an accident and a judgement goes against you, it could absolutely wipe you out, financially.
3. Consider a different class of bike. Sportbikes are sexy and tempting, but they are expensive. Not just the cost of the bike, but (as you found out) insurance, and the incidentals, like tires, brake rotors, chains, etc.
Personally, I'm fond of dual-sport bikes. A used one can be picked up fairly inexpensively. Insurance on them is LOW since they aren't on the thieves, cops, or insurance company's radar screens. Fit a set of semi-sticky tires on comething like a KLR650 and you'll be hopping off curbs with a big dopey grin on your face in no time.
Spend a couple of years on that. Hopefully, by that time, you've been a good boy and that record will be cleaned up. Perhaps the economy will be better and maybe your financial picture, as well. You can re-visit the sportbike realm with a clean record, and important rider experience.
Oh, and beware of the 'bargain' bike. The sales price may be only half the story. The bike may need tires, chain/sprockets, bearings, engine work, seals/gaskets, you name it. That leaves you with a $1500 bike that may need $1500 more to make it right. No matter what you buy, unless you know what you're doing, have the owner take the bike to your dealer/mechanic and pay the shop $50 to give it a look over. It could save you a TON of money in the long run.
You may not get exactly what you want, but at least you're out there. Good luck!
