Are you sure you can find a stretch with a safe road surface or shall we do it in one of these insignificant countries that at least have their roads up to standard? No wonder US has speed limits everywhere. Coming from Canada the difference was striking.
I'm sorry you can't handle roads that aren't newly paved. Do you want us to also arrange mild temperatures and rest stops every couple of miles (kilometers)? I'd like to see you attempt riding on the Brooklyn Queens Expressway. You'd probably have a hissy-fit. And are you one of those turtles afraid to exceed posted speed limits? I'm not as fast as I used to be (I have my moments) and don't see anybody obeying them, anyway. And BTW, I've been riding for 36 years, about a quarter-million miles.
Around here in the good ol' USA, riders and their machines have hardened and honed their adaptability to diverse road conditions, and makes for a more competent rider. I also believe that a lightweight motorcycle doesn't make for as stable a highway machine with the bumpy roads and wind-gusts. Billiard-smooth roads are nice but we can handle diverse extremes, usually even welcome it for the added interest and higher sense of awareness of road conditions at all times.
You should try the Kangamankus Highway in New Hampshire White Mountains, I've done that 25 mile section in under 20 minutes buncha times. With my ol' lady on board. Many sections have 125 mph+ straights.
