Washington DC to Madison, WI in 10 hours, 8 minutes (935 miles) including gas stops and the 1 hour time difference.
Saw two cops along the way, a quick flash of red/blue and then nothing after that... This was in 1998, and I was in my race gear - Dainese Safety Pro 1pc suit w/Knox back protector, Daytona boots ($700/pr), Kushitani GPR gloves ($160/pr), Arai Quantum e helmet.
My buddy and I used to purposely try to outrun the cops back in the day...now we've matured and only run when chased.
BTW, most speedo's are very "optimistic" at higher speeds - my 97 YZF showed 200mph, but top speed was at best 170. My 99 R1 shows a 208mph top speed, again top speed is about 170...Friends Hayabusa shows well over 220, actual probably around 190. That Hayabusa is scary...too heavy & waaaay to fast!
[Edit] Oh yeah, the nice thing about a bike is that it doesn't take too long to get up to speed...the YZF1000 did (according to mag's) 0-60 in 2.8, 0-100 in 4.9, 0-170 in 3100 feet, 70 - 0 in 135 feet. Not much road is required for a quick "test" (i.e. Interstates).
I never realized how fast 100mph was until I tried to stop quickly! Racing and track schools pay off big time. [/Edit]
