Counter-Steering
No B.S. Machine

The Correct Brothers
It shouldn't be alarming to me that riders still question
how to steer their motorcycles but it is. Apparently, even after 90 years when
it was first observed by the Wright brothers some confusion remains on this
subject . Yes, their first engineering attempts were as bicycle manufacturers;
the very observant brothers determined that tandem (one wheel in front of the
other) wheeled vehicles counter steer. That was and still is correct.
Sources Of Confusion
It is easy to see how confusion arises on the subject of
steering for anyone of us who started their riding on pedal bikes. The steering
is so light on a bicycle that riders have difficulty in separating the shift of
their body mass (leaning into it) with the slight effort it takes to
counter-steer.
Further confusion arises from word of mouth advice on
riding. I have even seen articles in usually credible national magazines
extolling the virtues of body mass type steering. Body Steering as it is called.
I have surveyed thousands of riders on this point. Most riders still believe
that some of the steering is being done with their body mass or weight shift or
pressure on the motorcycle's tank or pegs. Their estimates on how effective
these are in getting the bike to turn range anywhere from 10% to 90%, some
believe all of it is weight shift.
Swoopy Steering
If it weren't so grim, it's almost comical to watch a
rider who does not understand how steering is accomplished. You can see them
riding down the freeway trying and failing to change lanes by body steering and
still appear cool while doing so. I have seen it dozens of times. It goes like
this. The rider does a very swoopy upper body swing in the direction he wishes
to go but for an agonizing (to me) moment, nothing happens. There is a
perceivable lag between the upper body swoop and the bike's deflection from its
original course. How terrifying it must be to find that the bike doesn't
instantly respond.
Stiffen To Steer
Following that is a stiffening of the rider's upper body.
Only then does the bike respond and change lanes. You see how this works? The
rider's body is positioned off-center, from his swoop, in the intended direction
of the lane change. The stiffening on the bars creates the counter-steering
action, because he has either pushed on the inside bar or stiffened and pulled
on the outside one or a combination of both. This stiffening is actually a mild
panic reaction. Many riders have simply learned to live with the lag and to
think it is how their bike handles. That is false, a motorcycle responds almost
instantly to counter-steering.
Vague Technique
Riders have a number of ideas, which are vague and hard
for them to describe, on just how their weight shifting accomplish this so
called body-steering. "Throwing" their upper body mass to one side or the other
(the swoop) is one. Some say they just push down on the inside peg. Some say
they pull the bike over with the outside leg against the tank. Some say it is a
combination of two or even all three of the above methods. Do they work?
I'll leave it up to the tech boys to figure out the WHY
of motorcycle counter- steering. Their job should be to provide a simple
demonstration of how it works. The fact is that counter-steering is still being
argued in the halls of learning with slide rules, Physics formulas and
calculators. Many theories exist but no conclusive statement that I know of as
to why has yet been reached. Argue on boys.
Clear The Issue
My job is to make riding simple and to clear up
conflicting information that a rider may have on the subject of riding. Any
confusion translates into reduced control, as in the lag from swoop to lane
change, and confidence, as in the bike won't do what I want it to, when I want
it to. Riders don't like the uncertainty and love the feeling of confidence. I
decided to clarify this steering issue, body vs counter, very simple and very
plain. I reasoned that anyone who could see how it works and experience the real
steering procedure would have dramatically improved their chances of survival
against the perils of 21st Century Earth street riding. Steering must be done
and done quickly if a rider has any hope of confidently neutralizing those
perils.
Expert Opinions
I was actually in a deep confusion on this subject of
body-steering myself. Riders the caliber of Eric Bostrum have told me that they
do it to some degree, to help steer. Freddie Spencer has made a statement to
that effect and of course Reg Pridmore has made it the banner for his CLASS
schools for 15 years. Jason's STAR school has been written up as teaching body
steering as well.
With great to good credentials like that it should be so,
and even I was a little shaken in my certainty. Maybe there was something in it
after all. I hate to miss anything.
The Experiments
For my part, experimenting with pressure on the pegs, the
tank, adjusting my body mass and combinations of all three on the bike resulted
in nothing I would consider steering. In other words, something that could be
used in an emergency maneuver or to aggressively flick the bike into a corner or
through a set of esses.
Eventually I arrived at a potential solution to my
questions that would eliminate my opinions and/or misunderstanding on the
subject.
The Solution
Make a bike that has two sets of bars. One set as normal,
the other set would be solid mounted to the frame so they were not connected to
and did not rotate the forks. This, as my theory went, would answer the
question. And it does.
The Machine
Taking one of our Kawasaki ZX 6Rs and solid mounting a
set of bars 8" above the standard ones would positively isolate the various body
shifting from the counter-steering. If body-steering had any effect it would be
simple to show it. I created a bike with that setup. One necessary detail was to
mount an additional throttle on the upper, solid mounted, bars so the bike's
stability could be maintained as the user rode down the road. So we wound up
with two sets of handlebars and two operating throttles on the bike.
Dirty Exceptions
Before I go any further I want to address off-road
motorcycles. An off-road motorcycle will easily steer by pressing down on the
inside peg, and in conjunction with shifting the upper body mass, will go over
pretty easily . Still not what I would call good control but it can be done
fairly efficiently.
Again, I am not a true tech guy but it occurs to me that
the small contact patch on knobbies or dual sport tires and dirt bike steering
geometry, which is not intended to provide an enormous amount of stability at
speed, contribute to the reasons why steering results from weight shifts to the
degree it does on a dirt bike.
No B.S.
At this writing, we have run nearly 100 riders of all
experience levels on this double barred bike. It has made believers out of every
single one--in the actuality of counter-steering of course. Even at speeds of no
more than 20 to 35 mph, no matter how much you tug or push or pull or jump
around on the bike, the best we saw was that the bike wiggled and became
somewhat unstable. Did it turn? Not really. Would it turn at higher speed?
Absolutely not. Could you avoid something in your path? No Way. Could anyone
quick turn the bike? Hopeless! The best result was one of my riding coaches. He
got into a full hang-off position and was able to persuade the bike, by jerking
on it, to start on a wide, wide arc in the paddock at Laguna Seca, a piece of
asphalt that is about 500 X 800 feet. Like turning an oil tanker ship, start at
noon and be on the turning arc at around 1:00 PM. It wasn't smooth and it wasn't
very effective.
We now call this bike "The NO BS Bike". There are no
doubts in anyone's mind after they ride it that they have been counter-steering
all along. No doubts.
You can hear riders, who believed in the body-steering
method, laughing in their helmets at 100 yards away once they get those solid
mounted bars in their hands and try to body-steer the bike. They just shake
their heads. No B.S.
Dangerous Misconceptions
Now if you want to look a little further into this, what
you will see is this; riders who still labor under the misconception that they
body-steer are devoting themselves in a system that can do a great deal of
actual harm. Firstly, it is seriously misguided to add an additional series of
actions to the steering process. When it is quick, critical steering that is
needed to avoid something, that lag I have observed so many times in street
riders, could cost you your hide.
Adding 2/10ths to 5/10ths of a second, or more, to the
steering procedure at 60 mph means that you have just gone another 18 to 44
feet, or more, down the road before you started to avoid that muffler lying in
your path. Kids, don't try this at home.
The way things are going there will be warning labels on
motorcycles in the not too distant future.
WARNING: THIS VEHICLE COUNTER-STEERS. IF YOU DO
NOT UNDERSTAND COUNTER-STEERING DO NOT RIDE. SEEK THE HELP OF A QUALIFIED
PROFESSIONAL Riding Coach.
Bull Steering
Another recognizable error, resulting in excess effort
used to steer the motorcycle, is the attempt to turn the bike by bulldogging the
bars. An interesting combination of pulling up on one and pushing down on the
other rodeo style, like bull wrestling. No, repeat No, steering results from
this. None, zero, nadda, niente. Riders who think they can twist the bike into a
turn in this fashion simply have another false idea and get tired. The Bottom
Line
Steering a motorcycle results from the process of pushing
the inside bar forward, the same angle and direction the forks rotate in the
steering head bearings. You can also pull on the outside bar. You can do both
push and pull. That is what turns it, that is all that turns it
with any degree of accuracy, efficiency, quickness or
smoothness. That and only that, No B.S.
