ahhhh! I spent 20 minutes looking for that. I knew there was a video so I went to youtube and searched for everything I could think of: no bar turning motorcycle, body steering motorcycle, turn a motorcycle with your body...
glad someone got around to posting it.
A good resource, methinks.
I'd like to clarify my point a bit.
If you check out the videos, you can see that body steering does only a very little bit in making the motorcycle lean. Whether people are conscious of it or not, the primary input to get the bike turned is via the clip-ons.
If you're not getting the bike over fast enough, its because you didn't put enough input into the clipons, either by pushing or pulling.
Thats NOT to say it should be a jerk or yank as some are characterizing it. Its NOT. Its a smooth but deliberate motion. Once you get it over, then you should absolutely be light on the bars. By the time I hit the apex there's barely any pressure at all.
Thats not to say body steering is useless, either. You can see that body steering on the no BS bike does cause some
direction change.You'll also notice that it took some very abrupt and major body shift to get a very small change in direction. But body steering isn't, in and of itself, going to get you turned any faster.
There are piles of and piles of pointy-headed physics white papers that corroborate what the No BS bike demonstrates, and what non-naturals like myself have come to realize.
