Not only is there more danger, but if you do lose traction, you are going to slide a lot further, or if you hit something, stop a lot faster, as in sudden impact. Same lean angle at higher speed means more G forces.
Sport bike tires have a different rubber compuond, and will grip better, but you put enough force on anything, and it will slip, slide, move, whatever.
