That's a bit heavy for what I use and keep the weight between 12 and 14 lbs max. 6 lbs probably wouldn't be a lot of weight to many but you sound like someone who can recognize that difference. For me, how the bike handles ultimately has a lot to do with it's overall weight and so I'm also working to keep that under 50 lbs. Of the 6 motorized bicycles I have only 2 are aluminum but full suspension and the rack weight seems to get nicely balanced against the weight of the front forks.
Overall I agree though, steel is real lol, and love the old Stumpjumper, Bridgestone MB1 and Dback Ridge Runner I have.
