I just did 1,300 miles in 3 days. Including a 400 mile stretch into high wind. My opinion is that a windshield is not necessary. It kills the look and defeats the minimalist thing for which one buys a Bobber. Just my two cents.
But yeah, it does great at 70-80 MPH. I think it's a totally competent mid-range road-tripper. I was completely comfortable for 4 or 5 hours at a time. If anything, the wind kinda props you up.
