Using throttle to control cornering arc?

[OreoGaborio]

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.
