Ordered a private number plate for the bike when I registered it. Here in North Dakota (US) it's a little easier than in the UK, although they apparently check Urban Dictionary to make sure your "yeah, it's me Mum's initial, init" reason isn't really some slang for a ladies lovely bits.
As I mentioned in the "got a new bike" thread, my FZR in the UK was called "Florafumi" but for this one it's just "Flora".
