The fastest I've been on a bike was only 105 over a very short distance -- less than a mile. No windshield, so wind was very much a factor -- not to mention my puckered asshole. I do NOT riding at that kind of speed, especially on a public road.
On my Honda 919, however, I was only at 5 grand in 6th gear, with another 4 grand till redline. The guys who have ridden a lot faster than I have on a similar bike tell me the upper limit is 145, actual. (Indicated reads a bit more.) I believe them, but they're gonna have to do that without me.
