didn't drove all the bikes, so don't know them all, most are less heavy, but i can understand after 2 hr riding that people put another seat on it, 280kg is heavy and if you're tall, risers are needed, and you are still in the rain even with the screen on top position, slow driving isn't a pleasure with 280 kg below you and if you are large, you see your arms in the mirrors so it is not perfect for me
but it is a nice bike to ride with, just that you drive more then the limits before you know
and never, never empty your fuel tank , because he is to heavy to push
but it is a great bike
did i mentioned that it's a heavy bike?
