I have a Yamaha TW200 which is a great compromise trail & street mule but it tops out about 60 mph so freeways are pretty much out.

I also have a BMW R1200GS which is awful heavy for a lot of dirt roads since I am not a 6’5” muscular Austrian, (I’m 5’8”, 165, so you’d do fine) but I don’t regret it because it is such an awesome interstate touring bike. I was surprised that I like it better for highways than my Harley Road King & it does plain dirt, & fire roads just fine. Kinda pricey but I searched out a 1 year old lightly used one & saved 10K.
