OP, You just described the bike I bought two weeks ago. Suzuki V Strom 1000 V Twin, power to do 80 all day long with or without a passenger 50 mpg Plenty of cornering clearance Moderate seat height, I am 5 '10 and can easily get on and off and flat foot one foot at intersections. With the proper tires can handle a lot of different terrain
It's small brother, the 650 will do everything as well except will be slower carrying a passenger running highway speeds.
The Honda African twin would also be a great choice.
Those V-Stroms are supposed to be the do-all bike.
