Hello! Wow racing Nortons sounds fun! After the CBT you can only ride bikes up to 125cc. This makes it difficult to then do your A2 on a 200cc as you won't legally be able to ride it to and from places without an instructor present. IIRC there are no "musts" clothing wise for bikes except for the helmet. I'm not going to recommend stuff, I am sure as a racer you have fallen off at speeds much greater than you will do at the CBT but you probably also know the value of good protection! Gloves and lid will be provided if you don't bring your own, some places have other gear too. I still get confused about the whole A2 to full shenanigans so I can tell you for the A2 you will need to do a mod1 (slow speed maneuvers) and then a mod2 (road test) then there are limitations to what you can ride power wise and at some point you can get a full licence by previously mentioned shenanigans (I'm old so just went straight for the DAS).
