Are the 2008 and 2007 wheels, rotors, and IDS sprocket interchangeable. I picked up a set of wheels and sprocket from a 2008 ultra and want to put them on by 2007 classic. Everything looks like its a direct swap, but thought I'd ask here first.

 

Different bearings, 25mm, but it can be done.

 

As dawg said 25mm bearings so your axle and spacerswill not fit.
Also the 08 rotors are larger and may rub your caliber.
Your best bet would be to put in the 1" bearing in the IDS and put that on your 07 wheel. If your plan is to use the 08 wheels then you will need to use your 07 rotors and have the 1" wheel bearings put into the 08 wheels

 

OK, thanks. Really like the 08 wheels so I think I'll just change out bearings and use my 07 brake rotors. Thanks again.

 

Would you please post again after you are done I havea set of 08 SG wheels I'm going to put on my RK in a couple of months.

 

I dont think the rotors from an 08 will work on an 07. Just bought an 08 and had already had chrome wheels and polished rotors from my 04. I had to purchase the wheel fitment kit due to the differnce in axle size, dealer stated the rotors would not work.
