What are some sport bikes (motorcycles) that are suitable for big and tall people?

I am 6'6 and 300lbs and I really want to buy a sports bike. I have no idea the makers of the bikes or models or anything, but I want one with some power. But all the bikers I see are smaller than I am and can ride just about anything, but I can't. Are there any bikes that would be perfect for me considering my height and weight?
