I've been reading about putting 200mm rear tire on touring bikes. This is something that may go on the to do list for my street glide. Curious if anyone has done this. Can a 200 rear fit on the bike as is or do you have to make major alterations? Are there kits for this? Like I said, just researching right now. This will be down the list after 26" and a few other things. Any help would be appreciated.
