Scotty, I spent a good part of yesterday trying to explain to you what
really happens when you turn
a motorcycle. You chose not to believe it, came up with ridiculous
'arguments', put up a picture of
a dirt bike in a slide, argued against Wikipedia, expert rider videos,
and a Motorcycle Safety
Instructor. Then you started putting bull**** words in my mouth and
comparing me to Harry and Kevin.
After trying to keep a level head, I gave up. That's when I said I'd
just made up the whole thing.
By looking at Google, Wikipedia, videos, etc, you should have realized
I was bull****ting when I
said I made it all up. But I'm thinking that was the only thing you
took seriously.

OK, here's the real poop. Steering a motorcycle at more that 'parking
lot' speeds is done using a
technique called counter steering. The technique is called 'counter
steering' because it is
'counter' to the way we learned how to turn a tricycle. On a
motorcycle, we push left to go left,
and push right to go right, as was explained in numerous videos,
Wikipedia, and over a million hits
in Google if you plug in 'counter steering a motorcycle'.

Here are some nice pictures explaining the technique:

Established that yesterday. Motorcycle countersteers, corrects, and
steers through the turn... got it...

The process through a curve::

Yup, counter steer, then steer, then countersteer again.... got it...
but not "through the corner".. your own pics are clear.... thanks....


I swore I wouldn't get involved in this anymore, but I have to point out
something.

Scott, that "gif" image showing the proper way to take a turn is
deceiving and not really telling the whole story.

It shows a section where you counter-steer to enter and begin the turn.
Based on the diagram, you might interpret that you *stop* the
counter-steer while in the turn. That's what is deceiving about the
diagram.

The amount of counter-steer is actually maintained throughout the turn
because the forces on the bike and rider remain constant throughout. It
*has* to, otherwise you won't completely navigate the turn.

However .. if the rear wheel breaks free and aligns with the direction
the bike is traveling, the previously established counter-steer
requirement will be nullified. You may have to re-establish
counter-steer again however to complete the rest of the turn.

The pictures you keep referencing are worthless. Where you see pressure
on the handlebars in one direction, I see it opposite.
The amount of counter-steer is so subtle, you really can't clearly see
what is going on.




So what you are saying is countersteering isn't related to the direction
of the front forks in relation to the centerline of the bike, it's
related to the force applied to the front forks in relation to the
gyroscopic plane created by the tires? Ok, that makes more sense...
