Our unique, bolt-together design allows the license plate to be mounted horizontally or vertically on either the left or right side of the bike.

You can bolt this bracket to your axle, shock, or weld the included raw steel slug anywhere on your frame and clamp it to that. The axle mount hole is .787" diameter, which is compatible on Harley's with 3/4" axles and Metric bikes with up to 20mm axles. TC Bros. exclusive Hardtail-Proof™ rubber mounting system isolates the tail light from vibration, even in the most demanding rigid frame applications. This ensures reliable operation and longer bulb life.
