What mods will be necessary to replace the 16" front wheel on an '08 FLHX with an 18" from a 2010 model?

 

If you have a 25mm axle I think U only have to change spacers. I"m doing the same
On my 07 with a 1in axle have to xchage bearings and spacers for 1 inch or axle and spacers to 25mm someone had a thread on doing this if U do a search

 

There is a thread on doing this, if U have a 25mm axle just change spacers. I'm doing the same on my 07 and must either change, bearings and spacers to 1in. Or go to a 25mm axle and spacere. Forks well work either way.

 

Sorry for posting twice
