I have done a few. BIR, VIR, Pahrump Raceway, and our technical college has a driving course that I have done a few advance rider sessions, not really a track day but kind of.
I have only had my falco out once and it was this past summer. Otherwise, I had an old beat up FZR that was a blast on the track. Now with the Falco, I hate to even risk dumping her...
Maybe I will get another track bike someday... :idk I would love to do more.
