I’ve taken the class and I’ve had my Ninja road ready since Friday. I haven’t practiced u-turns since I got the bike and when I had to do one on a dead end road it was harder than I thought. Part of the problem was knowing that outside the lines would be bad because of all the grass, weeds and junk there. That led to a form of target fixation where I was thinking about not going off the road that it messed up my u-turn.
I think with some car park practice I will be able to manage 20 feet. Right now that road has too many distractions for me. There are no consequences for going over the line in a car park.
