I took mine to track not too long ago.
Despite sport touring bike, it is very capable on the track. As big and heavy as it is, I was surprised at how flickable the bike was.
I am not sure the purpose of your question. If you don't already own one and think of getting one and you can only have 1 bike, then don't hesitate to get it. It is one damn good machine! It is the one bike does it all.
If you have the luxury of owning more than 1 bike, then you better get track oriented bike.
I have 2 pics in my gallery, http://www.vfrdiscussion.com/forum/index.php/gallery/album/6853-track-day-with-big12/
Forgot to mention: I signed up with the novice group on that trackday, but I did push the bike hard.
