145-150 on the vmax speedometer on a nice deserted U.P. road 6 years ago. Now about 4-5 times a year I get up to 135 mph at a deserted army air base, but generally like to play in 0-100 range. M/C top speed may change this summer since i will have a '03 FZ-1 that has DW 4 into 1/ Stage 2 jet kit and timing advance kit to ride, it's fast at least compared to Redbone!

In a car the tops has been 130 in my buddies '84 Vette, on I-285 near the
Dunwoody exit! (Rollie will recognize that area) But that is probably not too unusal for I-285 back then ('87-'88) because if you weren't doing at least 80 in the LH lane you were blocking traffic.:biglaugh:
