PM Radial 4-piston calipers, right chro

Radial mounted calipers are quite common on GP race bikes and hyper sports since a few years. By design, radial mounted calipers are stiffer than traditional calipers and hold alignment with the rotor much better. The result is better brake pad contact with the disc rotor, better braking performance and minimized heat. These calipers fit 2000 to present stock Harley forks with the use of radial mount brackets and hardware kits listed below. They also bolt straight onto forks with 108mm center-to-center radial brake mounting tabs and use spacer bushings between caliper and tab to adapt to your diameter disc brake rotor.
