After a light dinner last Thursday, I jumped on my bike to ride home. It was a balmy night. About 300m down the road, I was pulled over by a couple of motorcycle cops doing routine RBT's. They were positioned on the side of the road. After being breathalysed (zero reading of course), the officer asked me to remove my helmet. I immediately thought something must be wrong. All he wanted, though, was to chat about my bike (in an admiring way). He was being very friendly and we chatted about the bike, parts, etc. He then pointed to my number plate and, in his exact words, said: "Mate, I'm just letting you know that a lot of cops won't like this. It's illegally placed" (my bike has a tail tidy). Then he went on, "me personally, I don't really give a ****", and we both had a good laugh. After explaining the ADR rules, he said "Mate, I have to give you a written warning for this. It's not a defect notice. You can do what you want with it - if it was me I'd probably just chuck it in the bin". So he duly wrote me the warning, and had a few more minutes chat about bikes in general. I asked him about the BMW drive shaft he rode, and then we shook hands and I rode off, feeling so much more positive sentiment and faith in our police's public image.
