I have sportbike also and wear an icon full helmet for that, it does not fog unless raining.
For the victory I have a GMAX 55 half helmet. It is OK. As far as comfort its good, but I don't like how the sound bounced off of it. I have victory slash pipes and my ears will ring for a day if I wear that helmet for 100 mile ride. I'm selling that helmet and going with a 3/4 open-face retro for now and going to see if thats any better. my .02
