Nah, I just got one of those flimsy ones and used some double sided extra strong tape down either side of it, Works a treat and comes off without leaving ****ty sticky residue too :D
nah, I mean I've had police follow me for miles with it like that and they don't say ****. You can get a glimpse of it thanks to the shoddy DT suspension. the back of the bike sits perfect when you're sitting on it for them to see. If you come across a tosser cop though then I don't doubt they'll say something about it, at best they'll ask you to reposition it. I've had no trouble :)
