I am making my way through "A Twist of the Wrist II" for about the 5th time, only this time I believe I am starting to make sense of what Keith is saying, this is because I am asking myself questions to further understand and fill in the gaps I have in my model.
For example...Rule #1 "Once the throttle is cracked on, it is rolled on evenly, smoothly, and constantly throughout the remainder of the turn."
The question that I am asking myself is particularly about the "constant rolling on of the throttle throughout the remainder of the turn" part.
I understand that the tyres contact patch is usually 40/60 in terms of area available for contact with the ground and hence traction. So the cracking open of the throttle will move the static/constant mass of the bike/rider combination from the 50/50 to the 40/60 ideal, matching the contact patch area.
If however, the throttle, despite being cracked open is held constant at some point through the turn (not chopped), then the acceleration would decrease...the bike would reach a constant velocity and as a result the distribution of the bike/rider mass return from the ideal 40/60 back to a 50/50 distrubution and therefore no longer take advantage of the ideal contact patch area distribution (traction) available from the tyres.
Sorry if this rather complicated and repetative...but its where my understand is at the moment
