Because most experienced riders who enjoy this have learned to take it to the track!
I enjoy flying too...yet decided why risk it...especially when track days are meant for this. You will never learn the same amount of skills riding canyons as you will out of a track day! NEVER!
Better yet, do a season of racing and see how well you do! Chances are you will see what "fast" really is. I don't know you, so going by your odd comments of "CO is a racetrack" I do not see a ton of experience.
EDIT: Seriously though, I am not trying to lecture you…..I was once like you and thought I was indestructible on a bike too. I unfortunately have seen a lot of injuries and death over the long time I have been riding and that is what makes me talk this way. I had people tell me the same thing and I listened and now I guess I am telling you, but it is only to try to help you see that your thinking is only going to get you hurt on a sportbike eventually. Take the advice or leave it....I can't force you
