You need to do a CBT, before you can ride anything over 50cc and upto 125cc
i think you can ride a moped without L plate and a 125 on L's once a CBT is completed
but the CBT only lasts 3 years?
they just changed the learner tests last week also its a right fucking pa-lava now

CBT lasts 2 years, but yes you can ride anything upto 125CC, SO LONG as you are 17 or older!
You are a learner in both cases and thus require plates, remember a CBT is not a license, it's merely basic training, you do not have a motorcycle license and can not carry pillion passengers.
