It was a joke about the Harleys. In Ride Like a Pro, they use many different bikes.
Do a search and you'll find there are MANY different techniques in doing U-turns, so find the one that works for you.
For me, I do everything wrong according to just about all techniques, but who cares, I can always do a U turn even on a narrow road for only two cars with a curb that allows no error. That is when I do it my way. When I get stupid and think I must do it "right", I screw up.
Maybe it's because I have so many bad habits, it throws me off to try to correct them. Maybe I have brain cells missing everyone else has. Till this day I can't figure it out, and I'll admit, deep down inside it bugs me why am I so different?
