That one shot where the road is an S and the clouds are stacked to the horizon and the supermoto is laying it down ----- poetry! Well done!
The other ones are nice too, but if I may offer a little CC, it's hard to get good dynamic shots when the rider is leaning away from you and looking away from the camera. A couple of shots are the classic - rider tipping it in, aiming for the apex.
Here's one of me from many moons ago, when I did that kind of stuff. Summit Point, Jefferson Circuit, very slow, but you couldn't tell from the shot! I forget the photographer, but he was well-positioned for sure...
