Wheel / rotor fitment question.

I’m a novice to wheels so please bear with me. I have a general fitment question. I have a 2007 FXDB with stock 17/19 wheels.
I want to upgrade to an 18x5.5” and 21x2.15” set of RC wheels. I already know that they’re set up with 1” bearings so my 1” axle is fine. No problem there.

Can I use the stock rotors and will they bolt right up without modification? Or, do I need the matching rotors? I’d rather use the stock rotors.

Can an I use my existing stock pully or does a new one need to be installed? I’m not sure how pullies relate to wheel size. So this might sound like a dumb question to you. I have no clue.

Anything else I should be aware of?

Thanks in advance for any advice.

I think you're fine since your bike has the larger centering holes on the hub. are you buying new or used wheel? if the wheels are made for floating rotors you will need different rotors since they mount out farther from the hub. you can get 280 an 300 mm rotors so no issue there.
