Oooo!! Fresh can of worms!!!
We need a bit more info..
Are you going to go off road at all, and if so, what sort of terrain?
Do you have a price in mind?
Do you ride in the rain much?
Are you changing them yourself?
Are you an aggressive road rider?
Are you after grip or mileage?
Give us answer on these questions, and anything else you can come up with, and we'll try to narrow it down to something that you'd be happy with..
If you don't answer these questions, you'd be better off opening up the Motorcycle-Superstore.com website, picking a number, closing your eyes and clicking until you come across a tire that'll fit your bike.
