I have a 1997 fatboy. I have found some other powder coated fatboy wheels that are 18x3.5. Will these fit on my bike? Thanks for the help!

 

I'm certainly no expert, but I believe it's been done. You'll just need to keep within your tire width limitations and get bearings to match your axles. Best to check with manufacture info though.

 

The 97 wheel is the same through 2006 and in 07 the Mo Co changed their Fat Boy wheels. The new style wheels have the "bullet holes" and are 17" in diameter with the rear being wider to accommodate the 200mm tire. If the wheels you have are indeed 18x3.5 they must be aftermarket and may fit. You will need 3/4" bearings and the front must be able to accommodate your single disc. You may need custom spacers and or a disc spacer, the only way is to mock them up and see what you need. To answer your question if the hubs are set up for single disc then yes they will fit.
