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.
???
It would have to be a dynamometer with a wind tunnel attached, since they only measure force (or horsepower).
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.

It's people like you that killed Tinkerbell. I've seen a new bike that was less than 4 hours out of the crate at the dealer's that turned in an honest 188 mph, as measured with triple stopwatches over a 2-mile stretch.
It then went home where the owner began the upgrades intended to see 200, in hopes of eventually hitting his goal of 222.
Believe it. Your average Suzuki Hayabusa will do this right off the showroom floor using pump gas. Many more models will do the same with a simple swap of the ECU IC. The dealer will hand you the keys without any skill test, sanity check or even a license check. All you need is enough cash for a down payment. You too can be Superman!
Don't forget your helmet. You'll need at least one body part intact for identification purposes. Dental records work the best . . .
Lots of bone stock bikes will pass 170. Currently, the Jap manufactures are voluntarily putting 300kph electronic governors on their bikes. Defeating the gov is the first mod a lot of these guys do now.
