Our unique modular design allows the license plate to be mounted horizontally or vertically on either the left or right side of the bike by bolting it together using the pre cut mounting holes in the bracket. We also include two different mounting brackets so you can either bolt this bracket to your axle or weld the included raw steel slug anywhere on your frame and clamp it to that. The axle mount hole is .787" diameter so this can be used on Harleys with 3/4" axles and Metric bikes with 20mm axles. This is the most versatile bracket on the market! Your mounting options and license plate positions can be mixed and matched to give you the unique look that you are going for. Also included in the kit is the self grounding 12 Volt Brake/Tail Lamp/License Plate light with automotive style bulbs. The bracket is powdercoated gloss black and comes with stainless steel button head bolts/nuts. ALL STEEL BRACKETS ARE MADE IN USA!
