I've seen 115 on the clock on a hot day in the desert with a mild headwind. There was a little throttle left and it was still accelerating slowly when I backed off because there was some traffic ahead.
My Night Train has seen 110 while following a dealer wrench testing the OL's Nightster for high speed wobble.
Fastest I ever drove anything was 160 Kt in a Gruman AA5B Tiger.
