I started riding motorcycles/mini-bikes at about 9 or so years old, riding on the street since about 13 or 14 (early/mid 1970s), and this thread is the first time Ive ever heard of counter steering regarding motorcycles other than the concept of power slides. I agree that its way overthinking and overcomplicating the process for this lady. Id suggest a small motorcycle, like in the mini-motorcycle size range, and just go ride it around on the parking lot, open area, whatever, and keep doing different stuff, eventually getting smaller turns or doing stuff quicker. There is zero need to explain counter steering, just doing it will explain it much better, and she probably wont be conscious of doing it. The only thing i can really relate to countersteering is a quick change motion of the bike to avoid a hole in the road, and done by feel and body motion, it seems opposite the normal motion, but it throws the bike sideways quickly then goes the opposite way (which you then counteract to stay going straight), but avoids the hole instantly. You could probably explain the concept in general without terms like countersteering, but its also just something thats generally learned by experience. Riding a bicycle with no hands may be an easy way to understand to lean the way one wishes to go. Same on a motorcycle, but she probably shouldnt be riding a motorcycle with no hands at this point.
