Switch bearings or axle?
I bought a used rc components wheel. Was told it was off an 09 SG but it has 1 inch bearings. Will a 1 inch axle fit my bike or can I or should I swap the 1 inch bearings for 25mm? Will I need different spacers? The 25mm are narrower correct?
Thanks for any advise

I just did something similar but I went the other way. I have a 2007 RKC and I bought a wheel with 25mm bearings and I changed out my 1 inch axle to the 25mm axle. I bought these spacers:

Everything lined up perfectly for me.

I got it figured out after some measuring. The RC wheel uses a narrower 1" bearing then stock harley 1". It's actually 15mm same as the stock 25mm bearing so all I need to do is swap out to stock 25mm bearings. I'm glad because if it was the wider 1" bearing that would have been a nightmare for me with spacers using the narrower bearing. So next question is there a better bearing than the OEM bearing?

Actually, 25mm is less then 1" by .4 mm. Close, but still smaller in diameter than exactly 1".
As for alternate bearings, if you are talking about the ABS side, no, there is no substitute that I know of.
There are substitutes for the non-abs side, but they are still single row bearings.
Many just change out the bearings when they change out the tires to be on the safe side. Just keep an eye on them.
Here's a picture of the OEM ABS and non-abs 25mm bearings. The ABS bearing is 3 mm thicker to house the ABS encoder mechanism.

Harley sell wheel installation kits with bearings, necessary spacer and other parts, so that custom wheels can be installed on a wide range of bikes. Far easier to install the same bearings as your stock wheels, in other words 25mm.
