You should buy a pickup truck and/or trailer to get your bike to the riding areas.!
The Savage in stock form is only 30 HP, and the top speed is just about what you are hoping to ride at for 50-100 miles. It really won't do that very well, as it will be running at a very high rpm where a big single cylinder doesn't like to be......and it uses a lot of oil when running like that. At 80 mph on a stock bike you will be running around 5,300 rpm at 80 mph.
If you installed a 97mm Wiseco, a performance cam, did some work to the ports, installed a better exhaust, did the double Kawasaki Pulley conversion, installed a 140/90-15 rear tire - you could pull taller gearing and probably get the rpm down to 4,000 rpm at 70 mph.....around 4,500 rpm at 80 mph. You will likely spend $1,500 or more getting this done, and it will require you to tear down the top end of your bike to make the engine changes. (You can substitute a chain conversion for the double Kawasaki pulley if you are OK not having a belt).
However - the Savage chassis really doesn't handle all that well at speed, and you would be far better off with a bike better suited to this type of use. A twin cylinder bike will be able to handle the kind of riding you want to do.....even my twin cylinder Ninja 250 could run 80 mph easily - and the whole darn bike was only worth $1,500 (And it was a blast to ride). The larger 300 Ninja would be a bit more money and better able to ride those speeds....the bodywork makes the bike far more stable at those speeds than the Savage is. The Kawasaki Vulcan S could also handle those speeds if you want a foot forward cruiser style bike rather than a sport bike.
For me the Savage is a back road fun machine - not an interstate bike. When I want to ride the Savage I choose the 70mph and below roads. Kentucky offers lots of alternate paths to using the interstates, and it takes a bit longer but the roads are more interesting. If you can find roads that are not highways and have slower cruising speeds - those roads are the ones you should be riding the Savage on - 65 mph and below is where the Savage runs best.
