This is a billet aluminum adapter bracket that lets a Harley-Davidson or similar bike run a 108mm radial-mount sportbike caliper on the stock-size rotor. It fits either side of the fork, and a dual-disc setup needs two brackets. The V2 adds M10x1.25 threaded radial mounts so you can run ARP hardware, and stainless steel mounting hardware is included. It is the cheap way to get modern radial caliper bite without a full big-brake kit, though it only works with rotors up to 11.8 inches.

Only a handful of ratings, all at five stars, so the sample is small. Buyers report it does what it claims: a radial caliper bolts up cleanly and braking improves.
The OG Front Radial Mount Brake Caliper Bracket V2 lets a Harley-Davidson use 108mm radial mount sportbike calipers. It is CNC machined from billet 6061 T6 aluminum with a hard anodized finish. It mounts on either the left or right side.
This version has M10x1.25 radial mount threaded fixtures, which accept ARP hardware (sold separately). Stainless steel hardware and a shim set are included. The hardware is designed for stock-size rotors up to 11.8". These brackets are included in the store's Radial conversion Big Brake Kits.
The bracket is sold individually, so a bike with dual disks needs two. It can fit spoke wheels with bigger rotors on stock 2000 and up Harley forks. Check caliper-to-spoke clearance first.
