These Super Smooth Motorcycle Brake Calipers are direct bolt-on replacements for your stock Harley brake caliper. These billet motorcycle brake calipers are made for custom Harley Davidson motorcycles (HD), custom choppers, bobbers and most custom motorcycles. The Super Smooth Motorcycle Brake Calipers are a perfect match to our Drilled Sprocket Rotor Kit, Slotted Sprocket Rotor Kit, Drilled Motorcycle Brake Rotors and Slotted Motorcycle Brake Rotors. These are the smallest custom 4 piston calipers available on the market and all hardware is hidden for a very smooth and clean look. We make also black motorcycle brake calipers for customers that prefer the “dark” look. Front and rear motorcycle caliper brackets are sold separately.
