I have a 2004 heritage and want to add a set of 18"wheels from the 2008 and up road king. I believe i have 3/4 inch axles, would i need to adapt to 25mm bearings and axles or does anyone know,can i just swap 3/4 inch bearings into the roadking wheels and mount them? thanks.

 

I'm trying to do the same thing on my 2004 FatBoy...I want to mount a stock 2009 wheel to the front. Can't seem to get a straight answer on whether there is a kit to convert the 3'4'' to a 25mm , or what parts I would need to assemble to do the convertion.
Did you get this sorted out?
