In some states here in the US, vehicles can use a vintage license plate vs a current one when registering the vehicle for road use. For cars and trucks in my state, you first have to register the vehicle as an antique. If you have a good pair of original license plates from the car/truck's year of manufacture, you can then substitute the vintage plates for the new, state-issued ones. This is pretty cool when you can put a 1965 license plate on a 1965 Mustang, for example. I'm not sure if it can be done with a motorcycle, but I'm checking into it. Is this offered where you live?
