I built a 98 Fatboy it runs good this winter going to do some other general maintenance so thought came up.

What is the largest rear tire that can be put on with no mods and what mods wold have to be done for it to go from OEM rear tire to 150 to 200 rear tire?

Any suggestions links photos would rock. With the state i live in I figure middle of Oct will put it up then I have until middle of april to get it on the road.

 

There are several wide tire kits out there. Here are some options and a photo for inspiration!

Thanks here is an interesting question. I plan on riding cross country wide tire kit with bags what do you think about comfort?

 

I would plan on having a custom seat that is designed for long trips such as one with gel/memory foam. I recommend you decide what you want to do with regards to which fat tire kit you plan to use and then find out what seat options are offered for those kits.
