Does anyone know if the axle sizes for 07 softails are the same? The plan is to purchase a 16" front wheel for a Fat Boy to replace the 21" front wheel on my Night Train. I know my 07 Night Train has a 25mm front axle, I believe the Fat Boy has the same size I just want to be sure.
Also, I know the from 07 to 08 the rear axles went from 3/4" to 25mm,how much of a difference is that really? Could a wheel for a 25mm axle fit on a 3/4"?

Thanks in advance for any ideas.

 

25 mm is just a tad bit smaller than 1 in
