True. My point was, if we were comparing 300lb bikes, +- a few pounds might be truly impacting.
MX and sport bikes have a hard time covering up weight gain.
But the Giant ADV bikes, for the most part, are approaching 600lbs! And that's without cargo!
So although I'm not suggesting weight doesn't matter, I AM suggesting a 590lb example might be every bit as capable as a 545lb example. And, it's entirely possible that a 590lb bike carry its weight better than a 545lb bike does. Or, a 580lb & 585lb set of bikes feel completely different weight wise.
Most importantly though, ALL of them are a beast to pick up off the ground. That's when their weight actually matters most. And there are no winners!
