I cant seem to find any single disc 21" wheels made for the touring bikes. I know I could just pull the right side rotor off and use a spacer but I'm going with spokes and would like to have a clean looking hub that looks like it came that way factory. Will I have to get a custom hub made? Or would a wheel from a softail fit with a spacer? Thanks

 

I dont think a wheel off of a softail will work as they are not the same width... FX 41mm FL 49mm. So I'm doubting the wheel is the same width. Your best bet is to contact one of the wheel sponsors on this site like Hogpro, or Costal Moto. They will tell you excatly what you need. Good luck!
