I am putting together a list on items needed for installing a 200 tire on a softail. I now that there are kits out there but you can do it at home for less money than buying a kit. I plan on including the spacer size, sprocket spacer( belt drive is not the way to go as you have to move tire over and the bike rides a bit funny. 180 is the limit for tire size if you want to stay belt drive and keep the tire centered properly. I also have the items for upgrading to a 1 inch axle for those that have monster engines. ( I broke every type of 3/4 axle from stock to stuff that had to be threaded with a machine!!! Tryed adding bearing supports still no luck. The 1 inch axle is the trick you can use FL bearings in your stock wheels and axles are no problem to get. Almost all after market frames are now 1 inch standard.
