Let me poke a little food for thought in here on tire choice.
Most of the discussion on this thread seems to be pointed toward touring tires. Touring tires are fine and many guys enjoy the long lasting high mileage these tires deliver. Avon Storms, Pirelli Angels, Michelin Pilot Road 2, etc are great tires but you must keep in mind they are touring tires. Limited traction whether you are straight up or leaned over, these tires have less traction than High Performance tires. Touring tires are by no means in the same catagory with performance tires such as Dunlop Qualifier 2, Bridgestone BTO16, Pirelli Corsa III etc.
Both are round and black. That's the only two characteristics they share. If you are a commuter and never ask anything of your bike other than getting you to work and home safely, a touring tire is by far the best bang for the buck. If you are an agressive rider, even if you are not a knee dragger, I suggest you consider a performance tire. A High performance tire will allow you to make mistakes that will put you on your head on a touring tire. It's extremely rare to find a street rider whom is capable of finding the limits of a tire without crashing. And may I remind you, one crash due to loss of traction will cost more than the $$ difference in many many sets of tires!
You are riding a heavy, high HP, high performance bike. The tires you choose is what ties this monster to the pavement. Put slippery shoes on her and you can no longer unleash the beast! Learning to brake late and throttle early will become a distant memory!
