First one was badass, makes me wanna go get my FZ1 and my leathers on and keep the revs about 8k non-stop and pin it leaving the corner and let that sucker eat. Second one looked like you had to do 120 all the time to make the curves interesting. I haven't seen the 3rd but looked at the road on the map, looks lovely.
What does your friend ride? Look like a standard with a fairing?
First one was the tightest curves with no room for mistakes due to mountain on one side and guard rails/drop off on the other side (Down Yarnell Hill), Second one (Vulture Mine Road) is more of a open long sweeping curves so yes high speed curves and the third one is just outside of Prescott and is call the white spars and is in between the other two... Not super tight but not wide open either... The best in my opinion.
We had about 30 other riders that day but they all bailed earlier in the day and us hard core ones stayed for the most enjoyable part of the ride... We had a Vstrom 1000 (That guy can out corner most sport bike riders and does track days all the time on the Vstrom) Then we had a FZ1 and he also rides track allot, and we had a Ducati race bike of some type... It was an older one and the guy was a little slower then the rest of us so not sure if he is in the video or not... (I did allow him past me at the end of the Yarnell Video so you can catch a glimpse of his bike there
then me on the Concours who has done a few track days but not a track junky like the other two.... Anyways we did about 375 miles that day and those three videos show the last of the 375 miles hence why most of all the sport bike riders bailed earlier in the day which was probably a good thing because some of them get in over their head trying to keep from being embarrassed from bikes like the Concours. lol
