For a whole lot of reasons, and based on personal experience from riding across the US, mostly the southern half, the West is the Best. Well worth the effort to ride there.
Far less traffic that east of the Mississippi, even on the tiny backroads.
Motorists in California, including log trucks, pull over to the side of the road to let motorcycles pass.
Motorists out west have the ability to drive in their own lane, and NOT cross over in every corner into my lane.
Whether carrying luggage and riding town to town, or daily rides from one central hotel, there is endless opportunity for riding out west. Riding without having to compete with the heavy tourist roads that are promoted in motorcycle magazines.
Elan Valley, this was 20 miles of mostly single track road which made for the best ride I've ever had on this bike, it couldn't have been better suited. As I approached the the top of one hill there was a guy sat next to his bicycle holding his hand to one ear and giving me the thumbs up with his other. put such a grin on my face!
On the east coast (US) the logging trucks do not pull over. Also some of the roads are split by the trucks, in the direction of travel - throw in frost heaves and you have a whole ton of fun winding through the mountains. I love it (not being behind slow trucks - but that's where 100hp comes in) , and rain or shine, the bike with standard suspension has taken everything in stride.
I've redone my hitch carrier set-up because my car is so tall. With a drop hitch I have cut down the insertion bar to 1/3 the original length. Super easy to roll the Hyperstrada onto the carrier now.
In my opinion, the more challenging roads for the Hyperstrada are those in the wide open spaces of the 4 Corners. This is because of the great distances that are covered, with little gas and high speeds which will tire a nearly naked bike rider.
Yes, there are tasty bits that reward the smaller bike rider:
Some bits are especially well suited to the Strada:
Sights to behold, regardless of bike, all the same:
I have found my favorite roads for the hyper are smooth, medium speed (40-60mph). The SP suspension does not fare well on the very goaty stuff, and like you said, the tall naked position is not the best on higher speed roads for long periods of time. In that sweet spot though, it's hard to beat!!
