A couple of decades ago, I pulled over for the state police, and got a ticket for speeds in excess of 130 mph. In a Nissan 310GX, believe it or not (I'd just rebuilt the top end of the engine). So it is documented (happened to be on a "farm road"). (209.2147 kph)
On a motorcycle, even further back, either 155 (249.4483 kph) or 170 mph (273.5885 kmph), I can't remember, on a bored out BSA flat track racing cycle. One unique feature of this cycle is that it had a big knob to adjust to tighten up the handlebars for these high speeds.
I can't wait for the German Autobahn cpf'ers to pipe in.
