How did this end? I have just read through the thread and sound like your having a dog end of a time. I feel for you. If I was you already with a cbt and bike I would have been going out with an experienced rider friend who could iron out any issues. I see you keep refrencing people who done a week's course, pass and can ride what they like, or carry passengers, and don't need to take any further brush up lessons, this is because they have jumped through the hoops, paid all the monies and proved they can ride safely and to a certain standard on the roads, but you never stop learning. If carrying passengers is that important to you then keep up with the tests ect but as you already drive why not take some time build some road craft and attempt your test again but on a larger bike, the only thing you should find harder is the slow manouvers you can't throw it around like you do a 125.
