Kuryakyn Curved Laydown License Plate Mount With Frame (BLACK) As long as you have to display a license plate on your bike, why not make it look like it belongs there? The rear fenders on today's cruisers are very impressive; the license plate bracket and reflectors are a different story. This streamlined License Plate Mount holds a 4" x 7" plate and is truly the final touch needed. Such a difference for so little money. Note: Kuryakyn part number: 3148.
