I'd like to get a new front wheel for my 2012 SG. What parts or mods do I need to get other than the wheel? PS. Why does ABS change what wheel I need to get?

 

ABS bearings are different from non-ABS bearings, you need to make sure you have the correct bearings for whatever your bike is equipped with. AFAIK you don't need anything else for a 19". I believe you may need fender spacers for a 21" wheel (only because I've seen them advertised for sale).

 

+1 on the ABS bearing. MC Baggers make a variety that will fool the ABS system into thinking that you have a stock wheel. I'm using one on my '15 FLT with a 21" front wheel. Whoever you're buying the wheel from will have answers regarding the need for fender spacers.

 

As the previous posters stated- you will need a non-ABS bearing and I believe you will need to replace the rotors. I think that is it. I am considering doing the same to my 2012 FLHX

 

Ah. Misunderstood. Thought he was saying that he had ABS.

 

True on the bearings for the ABS sensor. Whichever wheel and tire combo you decide and if using your OEM fender, need to check clearance. I have 21" in my sig pick.

 

YES...on ABS and questions on the fender spacers? Do I need a new fender or will the stock one fit with a 21"? I really like the look of those "wrap around fenders"...not sure who makes them.

 

FWIW and this is only my opinion.
About 25 years or so ago, I had a '72 FX with a 19" front wheel(first Harley).
I had painted my buddies '70 FLH with a 16" front wheel. I put painted parts back on his bike and did a quick little scoot around the block. Within about a month I had went out and purchased a '83 FLHP. Love the big wheel feel. Almost wish the '13 FLHTK was a 16" front instead of 17". Much better feel on the road with the big wider tire out front.
Again only my opinion.

 

The stock FLHX fender will work, however, you may need to adjust the mounting holes to allow for the taller wheel. I ran the stock fender with a 21" rim and Metzeler tires and it didn't rub underneath. I have heard that with some tires it will rub and burn the paint. I now have a KlockWerks Wrapper and like the looks much better, it really shows off the new wheel.

 

You can use your stock fender. Drill out the rear mounting holes to 3/8" and when you mount it back up, rotate the fender as far back as it will go before tightening up. Tape a 5'16 nut on the center of your tire then spin it to make sure it doesn't hit the fender. Good to go then. If it does hit drill the holes to 7/16".

If no ABS its simple. Can use your stock rotors but most change them to better looking ones. As long as the wheel is made for your year and model, the stock axle and spacers will work too. Good time to put in chrome spacers along with some polished rotors.
