Using throttle to control cornering arc?

Karl, don't take this personally, but the sooner you realize that ONE BOOK isn't the be-all-end-all of motorcycle riding, the better off you'll be. I'm sure you realize this already, but you seem to be stuck in that mode.

See my prior post. Increasing or decreasing your speed can have EITHER EFFECT... there are far too many variables involved to discuss them effectively on a message board, but I will say this...

Done properly, decreasing speed will decrease your turning radius, all other things being equal and you don't upset the chassis.
Done IMPROPERLY, decreasing speed will increase your turning radius by standing the bike up, making you run wide.

Done properly, (ie, assuming the chassis is stable throughout the turn) increasing speed will increase your turning radius.
However if your chassis is for some reason a little unstable, increasing throttle position will stabilize it which can tighten up the turn.

So in reality, you're all right.... but you're also all stubbornly ignoring the other side of the argument... THUS brings me to why I believe OTB (and others) often give up trying to waste their time arguing on internet message boards, NOT because someone don't like their opinion, but because the other person is too damn ignorant of all the variables that can change the outcome of a given situation.

All curves aren't the same either. Going up Golden Gate Canyon, the first curve is a broad, 50 mph sweeper. Less than a hundred feet later is a blind, decreasing-radius, 15 mph curve in the opposite direction. Guess how many cars and bikes cross the double yellow there? There was another one further up the canyon, but they blasted away the canyon walls to make it a 20 or 25 mph curve.

I don't know about curves where everyone else rides, but most of the curves on my roads only last three or four seconds. Then I'm setting up for the next curve. A second or two to downshift and apply the brakes before the curve, one second to lean and keep the brakes on until the apex, and one second to apply throttle out of the curve. Going uphill might be earlier throttle, and going downhill might be longer brake. But except for leaning off the bike and pushing on the inner handlebar, my brakes are what I use to control the cornering arc.

I agree... that is, until you reach the apex, right?

and in this case, my definition of apex is the point at which you stop turning IN and start turning OUT.
