I had to go through a course like that to get my motorcycle endorsement in the state of Nebraska a few years ago. It was obviously a much easier course, but they did have a 4 foot wide 90 degree square turn, and I was doing the course on my Suzuki VL1500. I made it on the first pass, but the lady officer told me about a 65 year old man who tried it before me on a Boss Hoss. He laid the bike over in the corner, and they had to radio for multiple officers to come to the site to help him pick the bike back up on its wheels. He failed.

Tharell your link didn't work for me but if it was his slow ride he killed it there too. I ride a Road King which is essentually the same bike he is riding. They go slow really really well and balance great. I feel I have pretty good riding skills and I can rail a Harley pretty well but this dude would hand me my ass.
The jap only put his foot down when he had to turn after stopping. Both videos were damn impressive, but that guy on that Harley was fuckin QUICK

Natural selection favors Smart people, so nature selects morons to be slow and dumb for tigers and stuff too eat. But in our modern world there just aren't enough tigers.
