I don't believe an unmodified bike will do 170 on a dynometer or even a test track, let alone heavy traffic on the interstate.

Before the manufacturers put limiters on them, the Kawasaki and Suzuki were both clocked by motorcycle magazines on test tracks at over 190MPH, and IIRC, one hit 197MPH.

However, the EU threatened to slap a 100% tarrif on the bikes if they could exceed (I believe) 300KPH, so they added limiters to keep the speed "down to" about 180 - 185 MPH.

I don't believe an unmodified bike will do 170...

I don't doubt that they can. Here in Mobile, AL I was cruising to work the other morning at around 85 mph. I was passed by one of these crotch rockets, traveling on only his rear wheel, leaving me in the dirt. He was leaving me so fast it looked like I was in reverse.

Cordially,
