Correct! Even some of the 13 on down bikes need minor modification to the rear fender mounting holes. But the closer fitting 14-15 bikes REQUIRE IT.

You can get them cheaper if you shop around.

The overall diameter is about 1" taller on a 21" front wheel set up over stock, thus that is what you should raise your stock fender by.
Brackets are inexpensive - replacing the front fender & paint is not

With the correct tire, yes. Many people the the 2013 down bikes just *****-nilly bolt on a 21 inch wheel and tire and get lucky. They have no issues and ride away. Others are not so lucky and burn the paint on their fenders. Once you bolt the 21 on, CHECK CLEARANCE! A 1/4 is a safe number. If your not gonna have the clearance you need, usually drilling out the rear fender mount holes with a 3/8 drill bit, and raising up the fender is all that's needed. Its a quick simple exercise that takes maybe thirty minutes. Or don't, just bolt it on and hope your tire never runs low on air.

yup, I "***** nilly'd" my wheel on with zero problems a few years ago, so did a handful of friends riding 2015s on down. Multiple ways to check clearance once the wheel is on, before you start drilling or buying brackets.

I had a 21 on my '09 Streetglide. Just bolt it up, make sure the tire is inflated properly (maybe slightly overinflated), tape a 1/4" nut on it and spin the tire. If it hits the fender then drill the back holes out a bit and tilt the fender. I had to do this on that bike and it was fine for over 70K.

I'm throwing the BS flag on that one. No chance you can bolt a 21 under the new low profile Rushmore fenders without modification in the form of brackets or some other mod. Never happen. The old style 13 down, sure. But not the OP's bike. The new style fender sits much lower over the tire and does not have enough room for the modern 21 wheel tire combo.
