Hi Rev, why did you assume I'm an illegal rider?
First of all I passed my car test before 2001, so I can ride a moped (50cc or less) with no need for a CBT, and I believe without the need for L plates.
Secondly, I did take a CBT because I'm not stupid enough to get on a bike and go out on the road without any sort of training. And I have L plates too. Having said that I have now derestricted the bike, and in doing so it would have been illegal for me to ride it if I hadn't already done the CBT.
