www.hog.com - easy enough huh?
When you buy a brand new bike from an authorized H-D Dealer, you are automatically enrolled into National HOG. Your membership is created with the same paperwork that the dealer sends in for the bike's warranty. This one free year of membership with National HOG is courtesy of the Motor Company. Some dealers also choose to throw in a free year with their local chapter. To become a member of a local chapter, you first have to be a member of National HOG. So basically, if they enroll you in a local chapter, you are already a member of National HOG.
By reading my previous posts, you would think I work for HOG. Thats because I do

I'm writing these posts on my own time from home though, because the administrator of this site decided to block access from the HD Corp HQ in Milwaukee. (just a bit strange imo) So please don't innundate me with questions, I don't ask you about your job on your free time! I'll try to help a little bit here and there when I can.
As far as HOG's benefits, if all you plan to do is buy parts and go to a rally every now and then, you aren't taking full advantage of what's available to you. One Fly and Ride rental (HOG members only bike rental in select locations in the states and beyond) VS a rental that the public could purchase (much more expensive) will save you enough money to more than pay for your membership at $40/yr. Not to mention reimbursement for money paid on a completed Safe Rider Skills course.
Those are just a couple things that makes it worth being a HOG member.
For more info, check out the website above or look over the membership manual that came in the package with the HOG Touring Handbook and pins/patches etc.
