Ive heard of DAS, A2 and A1 motorcycle tests. What are the differences between these tests?
In essence nothing. You could argue that for DAS tests the examiner would be a little more picky when they know that you could be going out and riding a Fireblade when you pass. The type of licence you get is simply dictated by the type of bike upon which you take your test. See the table at the end of these FAQs for the bike/category matrix.
