I have a GPS mounted on the Busa with ram mounts, and I have seen a GPS-verified 170mph in 5th gear at redline.
Unfortunately, the crosswind got to the point that I wasn't able to get into 6th and see how much further I could take it safely. She was pulling very strong through 5th, so I am curious how much more is there.
This test was completed at a top secret high desert testing facility, etc. etc.
