If anyone that is running a stock springer with the brake on the right side could measure the distance from the bearing face to the outside of the brake rotor I would greatly appreciate it...thanks.

The XBones brake is on the left side sitting on the seat. The distance is the width of the bearing race which is 3/8" if I understand what you are asking.

 

Yeah I am trying to use a stock harley brake setup with stock spacers with a sportster wheel...I know I will have to space the rotor out to make it work and I was just trying to get an adea of how big a rotor spacer I need to get. On the wheel I have their is only 1/8" between bearing to the outside of the rotor.
