There are dozens of motorcycle related magazines and books out there. As I posted a while back I have recently read the book “The old man and the Harley”. But, I also pick up the occasional motorcycle magazine. I subscribe to Hot Bike and always seem to end up one or two more anytime I go out to the book or grocery store.
Below is a picture of some of the periodicals I read.
I JUST WANT 2 RIDE!! 
I read a combination of the Two Wheels (Australia) which is for new motorcycles and gear and Australian Motorcycle News (AMCN) for the race stuff.
IN the past I’ve read Australian Road Rider until the editor jumped ship and created Australian Motorcyclist. This is the one that I subscribe to now
My favorite motorcycle related magazine is RoadRUNNER Magazine. A little expensive at $29.95 per year, but a good read. I look forward to each issue. Here’s the link: http://www.roadrunner.travel
I have a box of my dad’s old Easyriders Magazines in pretty great shape I’m wondering if there is an outlet we’re these can be sold other than ebay???
You could try some of the Harley forums, the few that remain.
