Numberplate - Ageing hooligan?
 

I know theres some different rule re: number plates on v. old bikes, I didn't think it related to size though! Today I saw something I'd never seen before though. A very old (and very slow) classic bike had a white on black numberplate, but it was absolutely tiny. We're talking small enough that a weekend R1 rider would think it was taking the mick a bit. :D
