When it comes to mounting a license plate on a supermoto, finding a location can be tricky. Many supermotos do not offer any form of OEM plate mount, and you have to get a little more creative to find a solution on your own. Finding a good license plate mounting location may involve some fabrication or drilling.
A good license plate mounting location should have some form of attachment point to the bike. It does not need to be sturdy, but a couple factory bolts that you can attach your plate to will help out tremendously. Make sure you check to see what all options there are for mounting your plate in any location on the back of the bike.
License plate brackets can attach parallel or perpendicular to the surface, some will even allow you to bend or rotate them to a custom angle. When adding these plate mounts, make sure that the option you choose is compliant with requirements for your local jurisdiction, as some locations may have harsh penalties for an improperly mounted plate.
License plates are very light, and generally made of a pretty flimsy material. In some cases, you may be able to bend or fold the plate around the edges of something to help it attach and at the same time meet the requirement. Many motorcycles have very large or unsightly factory license plate mounts. One option is to get a fender eliminator kit to help keep the lines on the bike clean, while still having a legal plate mount.
