on a stock rim (1999) what is the widest tire that will fit on a sportster?

 

Not sure what you can do with a stock wheel. But here's what you can do with a kit. Same place I got my chopper kit.

i would have to guess a 140

 

I really like the kit these folks offer. Too bad they don't have one for the 2004 and later models. Hopefully, they will design it soon. Ive been toying with the idea of trying to put a wider rear tire on...

 

Just saw your post and was wondering what's your opinion of the chopper kit . I like the look but haven't found many people with them.

Thanks

I was also wondering the same thing but i was thinking more of just a 150 tire. That 200 is a little much for me is there anything you can buy to fit a 150 on the sporties without drastic modification?

 

Don't have it installed yet (hopefully next week), but I did quite a bit of research (and even rode a couple of bikes with the kit installed), and recently ordered one of the AME frontend kits for my recently purchased 2005 1200C.

The AME kit is a proven design, and is both TUV and DOT approved and certified. It's my understanding that AME has been in business since 1973, and their frontend kits have been in use for well over a decade. It isn't that easy to get the TUV certification, so it's a sign that the kit is strong, dependable, and went through severe testing conditions.

One reason I chose AME is because of the steel (not aluminum) components, and also the fact that you can get the complete setup with 41mm tubes and chrome lowers, fully assembled at the factory. The 39mm tubes others offer are fine, but I prefer the slightly larger 41mm size.

I also researched the geometry of the bike, along with trail dimension once the frontend was installed. Back in the "old days" we use to install raked triple trees and extended tubes on bikes without any frame modifications. Of course this threw off the trail demension, and the results were less than satisfactory.

The AME frontend setup is able to keep the stock geometry and trail dimension because of the way the lower adaptor works with the neck and tree geometry. You end up with a 14* extension (44* total) by adding rake at both the neck and the tree. Neck rack angle increases trail dimension, while tree rake angle decreases trail dimension, so you end up with a canceling effect on the trail dimension.

I ended up going with the 14*, 8" over setup with the 41mm upgrade which includes assembled chrome lowers and chrome caliper.

 

Please post photos after you complete the conversion. You have me very curious on the look.
