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.
TPMS Note: Beginning in 2016, Harley-Davidson started including TPMS (Tire Pressure Monitoring System) on certain CVO models and beginning in 2020, Touring bikes equipped with the RDRS system have TPMS as well. BST wheels use a 7.5mm diameter air valve and would need to be drilled out to 11.3mm to accommodate the TPMS valve. If your application has TPMS, please call us to discuss your options. We do not recommend nor warrant, any modification to the BST wheels unless they are completed by factory trained personnel.
Brake Rotor Note: Before purchasing wheels for Harley-Davidson Touring models, due to variations in the OEM wheels equipped on each model, please verify the brake rotor mounting size. Models equipped with 7-bolt rotors (Agitator / Slicer / Chisel) will still be compatible with the purchase of aftermarket rotors. See Brake Rotor pitch circle diameter (PCD) on the description tab to see what rotor fits this wheel. For CVO models (excluding (23-24) CVO/CVO ST) look over the engineered drawing to verify fitment.
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).
