I think perhaps the better question is: Can YOU handle 800 weekly miles of moto commuting, week in, week out?
Cruising at a quasi-constant speed between 55-75 MPH on a back road or major highway will be the easiest miles your bike can enjoy, without frequent braking, acceleration, speed changes, gear shifts, full power operation or major stress. Certainly much more benign for the bike than stop-and-go urban operation.
However, 800 miles per week of commuting before or after a full workday will put considerable wear and tear on the rider. A lot of time in the saddle. What about rain? Other inclement weather? Does it get cold in your area? Bad weather will exponentially increase the stress of riding. Do you have a car for bad weather days?
In any event, you should do all you can to reduce wear and tear on the rider:
Good quality protective gear, hi-viz, the full Monty, no skimping; ear plugs; a safe, comfortable helmet with a quality visor; a rainsuit if you will be rained upon; a waterproof tank or tail bag; handguards (with muffs if cold); an electric vest or inner jacket for cold temps; and certainly, a good quality windscreen to mitigate the fatiguing windblast.
The bike, if maintained and adjusted regularly, should hold up well, although at the present state of our knowledge and experience, the 390 engine's lifespan is completely unknown. You will want to look for long-wearing touring tires, rather than grippy sport rubber. You are talking about potentially putting on 40K miles per year. That will undoubtedly put the Duke to a longevity test beyond anything seen in North America to date. Sprockets, chains and tires will need replacing periodically, and it would be prudent to have water pump and countershaft seals on hand, along with a replacement head gasket.
The real question, though, is whether the rider is up to that much saddle time, day after day. You will need to take as much of the load/stress off yourself as possible, then eat well and get plenty of sleep. With fortitude, it's possible.
