If the rider is small enough, a 17/43 would allow them to cruise at 60mph all day long on flat ground (and no head wind) with the throttle at about 3/4 or maybe a bit less with the engine singing along right at 6000rpm. Toss in a hill or wind and that changes very quickly, but for the most part, as long as the engine isn't trying to pull along too much weight or wind resistance, it could easily handle long highway miles. I would still want an oil cooler just to keep things in check, because that little motor will still be under a decent amount of stress.
I know some smaller-than-me people on here have run as high as 17/39 sprockets, which would drop the revs even more and had great results from it. Me being so big really limits my gearing options since I live in an area with lots of hills. I need the grunt to pull me up them lol.
