gday I have a set of alloy wheels off  a fxd  to fit to my 2008 streetbob can anyone enlighten me on bearings (size or numbers ) and spacers etc will they take same bearings same axle as far as I've read it should be no probs just like some more opinions and am looking for a disc for the front 

Cheers Dave 

I'm hearing crickets Hutchy

hey Hutch, the O/D of all the bearings throughout the models are the same its the I/D and the thickness of the bearing that varies, just change out the bearings and spacers using the axle of the original rim into the new one if they are not the same, pending on the offset you may have to shim out the brake rotor ,you may also not have to but keep it in mind nothing ever as easy as it seems ay, well it never is for me anyway
should be easy, I put an 06 billet front on my 09 softy this way worked out fine
cheers mate

Cheeh s mate thanks

What year are the wheels off?

2008 uses 25mm I.D. bearings and axle, 2006 and 2007 use 1.000" and earlier than 2006 use 3/4"
