Not completely different. You learn to use your eyes on track as well. Learn what your bike can really do and be comfortable doing it. That's the difference. You can be going at a good clip all day and have one moment oh shit moment; one rider might ride that out and be fine because of the track experience, the other may not be so lucky. It happened to me on one of my last street rides, and I only had a handful of track days under my belt. I'd be on someone's windshield if I wasn't comfortable doing what I had to do to tighten my radius.
