could not read the article without committing to the site. so… never going to happen.
however, the above responses suggest this is about, “Counter Steering”.
a good overview is at https://www.tunedtrends.com/what-is-countersteering/
talks about how Honda did research into motorcycle dynamics etc.
Simply put, to turn left on a two wheel vehicle (at at not fall over pace), we lean left and the bars tend to turn right, ie counter steering. When understood it is an effective method of high performance turning, ie you push the left bar away from yourself and we turn left aggressively, we push the right bar and we turn right.
Adrian will be able to explain how aggressive counter steering on a motorcycle can help you turn faster; he was a classy motorcycle racer.
It is something to be done to achieve low lap times when racing or to simply go fast on a bendy road.
I believe it was Eddie Lawson (30 years ago) came in after a Superbike race, having not crashed but his bars were bent, that is how hard he pushed on the bars to counter steer.
The phenomena if understood and practiced, can make you a much faster descender and give you the ability to avoid danger on the road aggressively without falling over.
You need to link this with weighting the outside leg of course and not over working the tire grip. Is a lot to it, buy it is the correct physics as the acticle should explain.
I hope you find the article interesting.
