I don't know that I've ever actually went WFO on the throttle in first, but I do lay into it pretty good every now and then, but I honestly don't have too much of an issue with the front end
When I get into it I usually crouch over the tank, being so tall I probably put a good amount of weight close to the front tire. Second gear WFO is a little less often, but if I get a good back road with no traffic I'll put it close to redline and let her wind back down. I think she maxes at about 110 at redline in 2nd, which I honestly don't think is too ridiculous on a public street so long as you do it in the appropriate place. (110 km of course and theoretically speaking, none of this is real world application).
I can't believe some of you haven't opened this bike up in first or second !? I'm still dying to open her up full throttle in 3rd, 4th, 5th, and 6th
Haven't done it yet though
