So I am looking at a set of wheels off a 2003 fxsts the guy says we're made for a bad boy and will fit my 95, when I look at parts list on jp cycle it's days wheels will only fit up to 99... Will 03 fxsts wheels fit on a 95 badboy? The wheels are the same diameter and width

 

different axles, bearings, and rotor set up.

Not a bolt on application....

 

So if I keep my stock rotors, axel and bearings will everything work? Or will I need some kind of brackets

 

Front will work, back not so much. 1985-99 have 2" rotor holes, just run the newer style rotor on front. 2003's have 2.25" rotor hole, problem is finding the correct toothed pulley, your 65 tooth will not fit on the newer wheel (center hole is too small). If you can find a 65 tooth with 2.25" holes it'll work.

Both have 3/4" axles.

 

The new set comes with rotors and a pully, should they fit?

 

What HDude says but you also have to machine a little less than an 1/8" off the inside of the late model pulley to align the belt correctly.Belt change is also needed. I'm running a 05 Train rear wheel on my 96 Bad Boy with a 160-16 Metzler.Front I'm not sure about the hub width because I've never had the chance to measure the width of the 95 wheel compared to the 96-7 models.You have the cable speedo and I'm not sure that will make a difference.

 

Would have to change belt. What does a new Springer run a 70 or 72 tooth most likely 1.25"? Your Bad Boy will have a 1.5" 65 tooth.

If it's a 150mm yes (you can get a used narrow pulley cheap on ebay, if needed), if a 130mm should be able to get up to a 1.5" pulley in there. I'd look into running the stock set and see about a belt change, I'd verify what you gear ratio will be with a larger pulley.
