I bought this 21" Hogpro wheel used. It was off an 08 SG non-ABS. My bike is an 09 ABS.

Took it and had the ABS bearing put in the left side...easy breezy.

I'm looking at my stock rotor and it has these buttons on the rotors. 1 on each side where the outer rotor meets the inner portion. The Hogpro wheel does not have this.

Is this going to be an issue?

 

Buttons have nothing to do with the ABS system. They are there to help with distortion and vibration in the rotor from heat generated during hard braking.

 

Just the difference between a 1 piece and 2 piece rotor. Ride that thing.

The stock rotors on your 09 are "floating" rotors, the Hogpro ones are one piece. The floating rotors are marketed to be quieter in terms of brake squeeking etc.

 

Ok, just making sure I was forgetting or overlooking something.
