There are some variables to deal with like elevation at which you ride, full gas or not and especially rider weight. There are some of us willing to state we are pushing the 300lb range. If you are 170lbs, you could have a very different experience at different rpm and gears.
I would say though, in general, above 6k in first you are pretty much going to be off the ground in the front. I have rolled on in 2nd at 6k going WOT and have not pulled the front up, however, a hard run out of 1st and a quick hard shift to 2nd has got the front wheel dancing. Take everyones note and then I hate to say, you just need to find out for yourself. Your bike, weight, riding style and just how fast you get to WOT could make your experience a little different.
I just would not want you to listen to me or anyone else and only expect going to 12 o'clock after 6k, when for you it could get there quicker.
welcome, good luck and safe riding
