I'm looking at getting a mid 80s Nighthawk 650. I was wondering how good these bikes are? I'm looking to get one as a daily driver and was just wondering how comfortable they are and what kind of mpg could I expect from one. Would this be an okay first bike for me? What would be considered high mileage for one of these? The reason I'm looking at Nighthawks are because I really like there design, just basic, nothing fancy, classic looking bike. Thanks a lot!
