If he's looking at the F800R and NC700X, he should also be looking at the Triumph Street Triple, Triumph Tiger 800 (probably the Roadie), Suzuki DL650, Kawasaki Versys, Ducati Monster 796, Aprilia Shiver, etc.
There's a LOT of bikes crowding this segment, and you could easily spend a year researching and arguing over which to get. I suggest he try to get some seat time on these bikes if at all possible. Something like an NC and Street Triple are VERY different riding experiences. Our opinions are irrelevant if a bike doesn't speak to him. I was excited about the F800 right up until the moment I road one. I was kind of "meh" about the Street Triple right up until I pulled out of the lot to begin the demo (lots of grins). His mileage may vary.
