I'm looking to put a 200mm tire kit on my bike. Any suggested manufacturers? Input? I'm also looking for a kit that uses a 1" axle. A 3/4" axle that length seems a little weak to me. Especially with a passenger.

 

200mm is a lot for a Nighty. You may need a new swingarm and go chain drive. Not entirely certain but I'm pretty sure....

 

Just google wide tire kit for sportster and youll get a few different links. J&P also carries one as well.
