I've done:
158 on my R-6
115 in my Fiero
125 in my Firebird
My friend has a GSXR 1000 he's been 164, but the crazy thing is he was in 4th gear with 2000 RPM left before redline!
The scariest thing though was going 80 in my 1979 Blazer, all of the steering bushings were worn out and it walked badly. The only time I thought I was going to die.
