Yeh people put em on for exactly that reason, i remember having one on my fizzy, and most of us did back in those days. I think they look good, and after all they are a genuine yamaha part, maybe they should have put em on at the factory and gained a few more sales of bikes on the strength of it
As for the L plates i think they would look good, cos all of us had those like it or not, and if they were not fitted the old bill constantly reminded us to fit em
oh the good old days
