I had everything you have listed and i rode beside my buddy who was on his crotch rocket and he said i was going 80. I had mine shut off a couple times.

 

Stock 72-73

Piped (depending on pipe) 75-79

Highly modified (with gearing changes) 100+

 

stock 70-75 w/ pipes probally around 75-80 and highly modded w/ a banshee its N/A i no theres a banshee on hiper technology site dat has 225 BWHP!! idk wat dat would give him in top speed but theres alos a banshee going up a dune at 85MPH

 

i've been 110 down a country back road on one. very scary!!!

 

mine did 93.1mph on radar.. stock gearing with quite a bit into it

 

i was going down a railroad bed and my gps said 81 stock

 

and if u drop one out of a plain u could probly get it up to 200mph.... come on goin downhill dont count.
