Yep I would agree. Just cause a bike'll do it doesn't mean it'll do it comfortably and nicely. As a general guideline, you usually want a bike that has at least 20-30 MPH on reserve of the posted speed limit for highway riding. This is for a bike that you'll do lots of highway riding on, not short jaunts. Not to mention he is talking about steep inclines. You want the bike to hold an honest GPS 65-70 MPH up steep highway climbs. And on the flats you want a nice tall top gear. It gets annoying to have your engine buzzing like crazy all the time. A Burgman 400 would handle it, but may not be the most comfortable bike for this. The 650 would be ideal for this kind of ride with the extra torque.
