I did a DAS cousre in march this year (passed first time yeah ) honestly never been on a bike before that. The instruction i got was excellent, CBT was just as good, as a car driver, i do remember thinking holy f*** there is no one else to give it clutch or brake if i am being stupid, when we went out on the 2 hour road part. The training was adequate for actuall controls on the bike. looking back perhaps it should be split in to a two day course. but thats all retrospective as i had road experience. I think that worked in my own favour.. but I did get excellent teacher.
