I'm with "Dweller"-I've hit 130-ish +/- several times-don't think I'll prolly ever go beyond 140 on the connie (Did 140 in my cage and still pulling). That said i've read a h*ll of a lot of threads about some serious MPHs in our little group. I also believe the "take it to the track stuff "....done it ,on bike & cage both more fun than you'd think AND you'll learn quickly you are not and will not mess with top speed of any serious sports vehicle.
I think that leaves long straights of public roads using "best judgements" unless of course you have access to The Flats or The Texas Mile.
Its a bit nutty to me- but these thing are really fast Right??
