Do you know how to work on bikes? Can you handle turning a wrench almost as much as you ride?
If no, then don't get one.
I use to own a 2006 BDM and sold it for a new Ultra.
I wouldn't buy a AIH if you paid me. They are junk. IMHO
I traded in my BDM so that should tell you that.
Want more info on a BDM... here's a forum
Big Dog Biker Understand most there are pro-bdm (almost too much) but there is a great deal of info.
