Hi, I would like to get a motorcycle as a novice rider, the models I'm keen on are the Yamaha SR400 '78-'02 & Honda CB550 1978. These motorcycles are not listed on the N.S.W novice riders list, however, their similar models are listed (Yamaha SR500 1978, Honda CB500 '71-'73, Honda CB 650 '79-'82). So as you can see motorcycles with the similar specification and production year has been excluded for a reason that I need to learn. Can someone there could explain this to me? Furthermore, these bikes are listed under LAMS Victoria. Thanks heaps.
