I found this on a Harley forum:
"So, I have a question for all you smart guys. I know that the newer touring bikes have available laced wheels that run tubeless tires. Does anyone know whether those wheels will fit my 2005 RK without a huge fuss? I'd really like to get tubeless so out here in the booneys I might be able to plug and fixaflat a tire if I needed to. I just love the looks of a spoked wheel or I'd go for the mag types."
And this worrying reply...
The issue is the bearings. 25mm ID bearings (2008-up) are a tad narrower than the 1" ID bearings you need. So they won't seat deep enough in the hub.
So.....that means the wheel isn't machined as deep to accept them.
As well, the bearing ID is different. I've heard guys say that the difference is so small (1" vs 25mm) and they've bolted the wheels on regardless. Not so sure that's a good idea, and hoping the bearing doesn't move on the axle.
I've been talking with a friend who's a machinist about how to make a kit to make newer wheels interchangeable with older bikes.
The measurements are:
(3/4" or 1" ID) X 52mm OD X 21mm wide.
The 25mm bearing is 6mm narrower, (15mm) for installing the ABS sensor in all 2000-up FL model front wheels.
The 2000-2007 21mm me a rings are also double row ball bearings where the 2008-up 15mm wide bearings are single row, possibly explaining some of the premature failures."
Nice bike mate, but I've got a bit fixated on this one...
