The slow speed stuff is the hardest. That's where the parking lot comes in. I live right behind a school, so I go to their parking lot all the time to practice. They have painted spots for the buses to park in that are rather large and I will weave through them, trying to turn around without going over the lines.Rode it 70miles home and its probably 1000 to Florida, I'm good kidding.
Not all straight like stuff, and honestly slow speed stuff is the scariest. Highway merging and ramps didn't seem to bother me at all, but turning onto a blind intersection had me sketched out.
Back when I took the BRC and my test, I could barely make it through the u-turn box. I took the ARC a few years ago, and after doing that practice, I was scraping pegs in the u-turn box and had lots of room to spare on my turns.
My pro-tip for you on slow speed maneuvering is to use your rear brake. If you rev the engine up a bit, slip the clutch, and drag the rear brake, you will find that the bike becomes extremely stable at slow speeds. I was barely able to keep it up below about 20 mph until I figured out the rear brake trick and now I can roll along below 5 mph without a problem.
Still can't balance enough to keep it up sitting still, but I'll get that down one day. Until then, at least I'm providing some laughs for people at traffic lights.
