I subscribe to four different ones. Anerican Iron is great, with a lot of technical information. American Bagger is really well done, with a lot of install of parts. Hot bike Baggers is only about touring bikes, like American Bagger is, but has more to do with the touring experience, which is good, as well. And, the grand daddy of them all, Easy Riders. Nice bikes, and boobies, if ya are in for that sort of thing. they have only a few, if any, articles on baggers. But, I see them heading in that direction, as is most of the Harley world.
I also pick up a couple of others, but only when I see an article I am interested in. American Rider is okay, but not one of my favorites. But, on their website,
http://www.americanrider.com/, you can watch a weekly video segment, which I like.
