The 2008 SG had 25mm bearings from the factory, your 05 will be 1" bearings. You will need to change bearings and spacer to 1" or buy a 25mm axle. Either way will work if this is an aftermarket wheel, which being 21" I assume it is.
YES IT IS A CUSTOM 21' CVO WHEEL GUESS i WILL HAVE THE SHOP CHANGE THE BEARING TODAY FOR ME THANKS FOR YOUR HELP
When you say "CVO" wheel, is it a Harley wheel from their catalog? The reason I'm asking is some of the newer wheels from Harley will not accept 1" bearings. The outside diameter is the same on both 25mm and 1" bearings, but the width is different. Most late model wheels from Harley do not have bearing pockets in the wheel that are deep enough to install 1". Just trying to make you aware of possible problem.
Hogpro you are right i had to change it all the hub the bearings and rotors
wow I think I should have got a new wheel instead of a used one but it on bike now and look good I want to change the spacer to chrome can i do that Hogpro
