There is a difference between science and artistry. To watch a master on the track will give life to that concept. The person that can put those observations to paper has a special gift indeed.
While reading all of the above, several things come to mind:
Judgement
Visualization (mental)
Visual lead (looking ahead)
Muscle memory
Flow of motion
Mastery of mind and machine
All too often, I see sensory overload. It usually comes with the novice rider trying to "do it all now" instead of in stages with practice and experience.
While teaching people to ride, we tell them that the process is 90% mental, 10% physical. If it wasn't, Chimpanzees would be out riding the roads.
Keep it coming, Keith!
