For ABS equipped H-D models: Altering the diameter of the front wheel requires the wheel speed sensor to be recalibrated to prevent loss of braking. See ‘Technical’ tab for additional information.

For Harley-Davidson models equipped with factory ABS: When altering the diameter of the front wheel, the wheel speed sensor needs to be recalibrated to prevent loss of braking. Brock’s Performance now offers MC Bagger ABS Recalibration Bearings to eliminate this issue. These bearings eliminate ABS malfunction and warning lights when removing your stock sized Harley-Davidson wheel and fitting a 21” BST wheel. To order, select option “ABS Recalibration Steel Bearing Kit” in the bearing options dropdown (MC Bagger ABS Recalibration Bearings are not available in ceramic).
