RJVB said:I'll have a look at the pdf, but as far as I know at this moment, body steering works mostly because while leaning off the bike's RHS, you pull on the left handlebar and/or push on the right. In other words, you could just as well push on the RHS handlebar at once
What can be seen in the video is that COG variations do modify the trajectory. It's a pity we don't see the guy hanging off as if he was deep in a turn on a track, so we could see just how little one accomplishes.
Interestingly, I had a chat with a colleague about all this earlier. He explained how he does "body steering" on his Zodiac: he blocks the engine at a given speed and straight ahead, and then takes place up front. To turn right, he just shifts his weight to the right.
This works because of the boats width, the fact it probably is considerably lighter than an average MC, and the absence of gyroscopic moments that will counter any roll attempt.
Of course you can pull instead of push; the idea of pushing is that it's faster.
Why should it be fast? Because on the road it's in the emergency cases you really need to know what it's about.
The term "countersteering" is established, at least up here in the cold North, since quite many years, and the method has been taught in courses, both in beginners- as well as advanced racingcourses carried out by our largest motorcycle organization, SMC, under supervising by Keith Code's CSS.
Actually I think it was the Norwegians who were out first here. They wrote a book "Full Kontroll" (you can see it in Swedish here: http://www.svmc.se/upload/SMC%20central ... 0SVENO.pdf - guess the pics are readable in Frenglish as well. ) based on Keith Codes methods, back in 2001.
That book has been distributed to all of the 70.000 SMC members, and is spread among the Norwegians NMCU as well.
