Forgot to mention this yesterday.

I have signed up for a MC riding course at Excalibur Motorsports in
Plainfield.

I intend to put this left/right controversy to rest once and for all
not out of disrespect for your opinions but because you are wrong.

Not that there is anything wrong with that. :)

And I would point out to all you heathens who actually believe that
left/right nonsense that up until ten or so years ago, it was thought
that the curveball didn't curve - it was an optical illusion.

EXCELSIOR!! :)

Well, if they don't teach you to countersteer, you've wasted your money and

No, neither of us were wrong.

Good luck with the course.- Hide quoted text -

I just came back from a morning walk/jog and decided to take the bicycle out
for a ride and test the steering issue on it. Thought it would be a good
idea to check the air in the tires, but it has weird valve stems that I've
never seen before and a conventional tire gauge fitting doesn't fit on it.
I inadvertently let all the air out of the front tire fooling around with
it. The bike's a Trek Hybrid. I guess I'll have to go back to the dealer
later and get whatever I need to fill it back up.

I'll submit my steering results later.

Haven't really used it enough to form an opinion, plus I don't know that
much about modern bicycles. When I was looking for a new bicycle, the Trek
name was recommended in many reviews, so I decided on it. It *is*
reasonably comfortable and so far seems to be well made.
The Hybrid is designed for both road use and casual off-road trail use. It
can be converted to a true "mountain bike" by changing the rims and tires.
I doubt I'll ever need to.

Trek is either the last, or one of the last American made bicycles. The big
names (Schwinn, etc.) are mostly importers now of bikes built in China.
Lance Armstrong used a Trek in several of his Tour de France victories.

Despite 7 months of daily, fairly rigorous exercise, bicycle pedaling uses a
whole new combination of muscles and takes some getting used to.

The frame might be made in the USA, but I'll bet many of the pieces and
parts are not. Shimano? Naw. Bontrager? Well, some of his stuff is still
made in the USA, but most is not. Tires? Unlikely. But a Trek is a
damned nice bike.

Try steering with one hand, and lean only with the bike so as not to
introduce something else into the game.

My gosh, I've put up numerous sites supporting the idea. Do you think
they're there as a joke?

Here's an exercise in avoidance maneuvering (using countersteering) you can
do on the HD.

Follow behind a car, using a 2 second interval (always) between you and the
car in front. Ride in the center of the lane. As you're following the car,
you'll notice sewer covers, gas line covers, etc., as they come from
beneath the car. Use countersteering to swerve and avoid the covers, or
anything else that pops up from underneath the car. This is a good exercise
in city traffic. It will help you miss the chunk of 4 x 4 that fell off the
truck in front of you while on the highway!

BTW, I think Terry Colon is wrong, partially, in his description of bicycle
steering. Therefore, I sent him the following email:

"
Your article on countersteering was used in a usegroup as proof that it
exists. In your article, you state that countersteering isn't used much
with bicycles, because leaning the body is sufficient to get the bike
turning. (http://www.terrycolon.com/1features/bike2.html)

I disagree. I believe that leaning the body, without changing the geometry
of the arms, does initiate a countersteer which turns the bicycle. If you
lean left, and don't bend your left elbow to compensate, you will push on
the left handlebar, thus countersteering. Try riding your bicycle and
leaning while keeping the bike in a straight direction. It is very easy to
do. You'll notice that you compensate for the lean with the geometry of
your arms, ensuring that you don't countersteer.

Thanks for your articles, by the way.

Well I been kinda' busy the last few days looking for a new boat so I
have not followed this much, I do need to come in here quickly as I
have a little experience in this field having had my bike licence for
over 30 years now. I was riding one dark night back in the mid 80's,
middle of winter riding to work. I hit a huge chunk of ice/slush that
had frozen to the road, about the size of a cinder block. It knocked
my front end sharply to the left, turning my wheel left and started to
deposit me down to the right as will happen when a front tire looses
grip on a bike. Loosening up my grip preparing to eat asphalt my front
end caught and kicked the tire around to the right, now the bike is
turning right and laying down to the left, again the tire, because of
the rake of the fork kicked to the left, kicking the bike upright and
back to the left. This wobble continued about 3-5 times until the bike
stood itself right up again. I pulled over and cleaned my pants. The
reverse lean steer saved my ass from a bad hit and it was only because
of the geometry of the bike that it happened, call it reverse steer,
call it great engineering, either way it was one time I f*****d up and
did not eat pavement..

Remember not to be a speed demon.................keep it to a normal speed.
;-)


Countersteering is used at any speed, above walking.

Here, learn something new - especially read the last two paragraphs...

Lean by countersteering

When riding a bicycle or a motorcycle, countersteering is a method of
initiating a turn by a small, momentary turn of the front wheel, usually
via the handlebars, in the opposite (counter) direction. Like the book
example above, this moves the pivot point (the wheels' contact patches) out
from under the center of mass to establish the lean angle for a turn. While
necessary at all speeds, the need to countersteer becomes more noticeable
as speed increases.

Hence, if a rider wants to turn to the right, he first throws the bike off
balance by momentarily pointing the front wheel slightly to the left. The
center of mass of the bike plus rider will continue in a straight line, but
the contact patches of the tires move to the left with respect to this
straight line.

Once lean is achieved

As the desired angle is approached, the rider must then steer into the turn
to maintain that angle or the bike continue to lean with gravity increasing
the rate until the side contacts the ground. As roll momentum and gravity
then tip the bike over to the side, the front wheel must be steered into
the curve, and the curve is negotiated with the proper inward lean. This
process usually requires little physical effort, because the geometry of
the steering system of most bikes is designed in such a way that the front
wheel has a strong tendency to steer in the direction of a lean.

Adjusting or exiting a turn

Once in a turn, countersteering is again required to make changes to its
shape. The only way to decrease the radius at the same speed is to increase
the lean angle, and the only way to increase the lean angle, is again to
momentarily steer opposite to the direction of the curve. To the untrained,
this can be extremely counter-intuitive.

To exit a turn, countersteer by momentarily steering further in the
direction of the turn. This tilts the bike back upright.

At low speeds

At low speeds countersteering is equally necessary, but the countersteering
is then so subtle that it drowns in the continuous corrections that are
made in balancing the bike, often falling below a just noticeable
difference or threshold of perception of the rider.

Unconscious behavior

Countersteering is indispensable for bike steering. Most people are not
consciously aware that they employ countersteering when riding their bike
any more then they are aware of the physics of walking. Their body has
learned to include the well timed countersteering jolt. They may have
learned to do so while learning to ride a bicycle in childhood. Often
people simply assume that the steering of a bike is just like the steering
of a car. Their unconscious balance skills know better.

As is well-known in bicycle racing, the countersteering phenomenon becomes
evident when there is an obstacle preventing the wheel from
countersteering, e.g., when closely overlapping wheels or riding very close
to a curb. In these situations, the only way to initiate a turn away from
the obstacle is to come into contact with it, that is, turn towards the
wheel or curb in order to avoid crashing into it.[3] Lack of understanding
of this principle leads to accidents in novice bicycle races.

With all due respect, I question the safety of this exercise. First, I
would never ride in the center of the lane. That's where all the oils,
nails, and other road debris accumulate. Ride in the left or right
track. The road is generally cleaner. Your visibility to other drivers
is enhanced, and you have slightly more escape paths.

Secondly, concentrating on someones' taillights is bad driving practice.
Concentrating on what comes out from underneath someones' car is even
worse. You should be looking farther down the road to enable reacting to
what the driver ahead of you is reacting to.

It's also my experience that city driving, in traffic, is far more
dangerous, and takes far more concentration and awareness than highway
driving. It seems to me, your exercise only increases the risk. There
are far better places to practice counter-steering.

Looks like countersteering is the initial process in turning a bicycle as
one *has* to lean into the turn, even at slow speeds (where the lean is not
obvious).


My apologies to you and John. ;-)


BTW, I think Terry Colon is wrong, partially, in his description of bicycle
steering. Therefore, I sent him the following email:


"
Your article on countersteering was used in a usegroup as proof that it
exists. In your article, you state that countersteering isn't used much
with bicycles, because leaning the body is sufficient to get the bike
turning. (http://www.terrycolon.com/1features/bike2.html)


I disagree. I believe that leaning the body, without changing the geometry
of the arms, does initiate a countersteer which turns the bicycle. If you
lean left, and don't bend your left elbow to compensate, you will push on
the left handlebar, thus countersteering. Try riding your bicycle and
leaning while keeping the bike in a straight direction. It is very easy to
do. You'll notice that you compensate for the lean with the geometry of
your arms, ensuring that you don't countersteer.


Thanks for your articles, by the way.

Well I been kinda' busy the last few days looking for a new boat so I
have not followed this much, I do need to come in here quickly as I
have a little experience in this field having had my bike licence for
over 30 years now. I was riding one dark night back in the mid 80's,
middle of winter riding to work. I hit a huge chunk of ice/slush that
had frozen to the road, about the size of a cinder block. It knocked
my front end sharply to the left, turning my wheel left and started to
deposit me down to the right as will happen when a front tire looses
grip on a bike. Loosening up my grip preparing to eat asphalt my front
end caught and kicked the tire around to the right, now the bike is
turning right and laying down to the left, again the tire, because of
the rake of the fork kicked to the left, kicking the bike upright and
back to the left. This wobble continued about 3-5 times until the bike
stood itself right up again. I pulled over and cleaned my pants. The
reverse lean steer saved my ass from a bad hit and it was only because
of the geometry of the bike that it happened, call it reverse steer,
call it great engineering, either way it was one time I f*****d up and
did not eat pavement..


Those 'death wobbles' are bad news. I got forced off the road by a semi out
near Richland, WA. Hit a bunch of loose gravel. The wobble started, but I
had no idea, at the time, how to get out of it. So, the bike and I went
down, skidded for a looooonnng ways, and did a lot of damage to me *and*
the bike. (Like a total dumb ass, I wasn't wearing leathers or even a

Ok ... got air in the tire on the bicycle finally and pedaled off down our
long, sloping driveway.
To my surprise, although the effect is there, it is very subtle when
compared to that on the Harley, so much so that I had to try it over and
over to convince myself it was there.
There is absolutely no question on the Harley .. a gentle push will initiate
a major course change, but not so on the bicycle. I tried at various speeds
up to 14 mph and didn't notice a whole lot of difference. The effect *is*
there, but you actually have to be looking for it to notice and to not
confuse it with other balance issues. I can clearly see why a
non-motorcyclist like ShortWave could hop on a bicycle looking to experience
countersteering and wondering what the heck we were talking about.

I also have a new theory. I suspect that countersteering is more pronounced
the heavier the two-wheeled vehicle is. On the 1000 lb Harley (bike and
rider) the effect is very pronounced.
I suspect a smaller, lighter dirt bike would not exhibit the effect to the
same degree.

Anyway, I do it all the time on the motorcycle. As JohnH pointed out it's a
natural reaction to avoiding a rock or muffler or something in the road
ahead that's coming up fast when cruising along at 70 mph.

There have been highway accidents due to "wobble" loss of control. They are
usually caused by riding too fast while navigating a long, sloping turn in
the road and suddenly de-accelerating for some reason. I've never
experienced it (hope I never will) but have been told that if it starts, hit
the throttle to maintain control and slow down more slowly.

I suspect you are right. That big Harley front wheel has more of a
gyroscopic effect, which I'm guessing is instrumental to the counter-
steering phenomenon. The push left gets your left lean, but the
gyroscopic effect means the wheel will straighten so you can continue
your left turn. The same physics apply to a bicycle, but because of less
mass they are not as pronounced. At least that's the story I'm sticking
to.

Follow behind a car, using a 2 second interval (always) between you and
the car in front. Ride in the center of the lane. As you're following
the car, you'll notice sewer covers, gas line covers, etc., as they come
from beneath the car. Use countersteering to swerve and avoid the
covers, or anything else that pops up from underneath the car. This is a
good exercise in city traffic. It will help you miss the chunk of 4 x 4
that fell off the truck in front of you while on the highway!


With all due respect, I question the safety of this exercise. First, I
would never ride in the center of the lane. That's where all the oils,
nails, and other road debris accumulate. Ride in the left or right
track. The road is generally cleaner. Your visibility to other drivers
is enhanced, and you have slightly more escape paths.

Secondly, concentrating on someones' taillights is bad driving practice.
Concentrating on what comes out from underneath someones' car is even
worse. You should be looking farther down the road to enable reacting to
what the driver ahead of you is reacting to.

It's also my experience that city driving, in traffic, is far more
dangerous, and takes far more concentration and awareness than highway
driving. It seems to me, your exercise only increases the risk. There
are far better places to practice counter-steering.


If I felt it was unsafe, I wouldn't do it. If the traffic was heavy, I
wouldn't do it. Most city roads are not full of trash in the center of the
lane. Where did 'taillights' enter the picture?

You're correct about looking well ahead, but a motorcyclist must also look
directly in front. The eyes should be continuously looking for danger or
people, or dogs.

We used to get that wobble coming in 84 east bound just west of the
mass border, I am sure SW is familiar with the old highway. And you
can not just brake to stop it, you gotta maintain throttle and come
off real slow, and real out of control. My Bike used to get it at
certain speeds, somewhere under 80 I think there was a band where it
was real bad. The wobble I described in my almost wreck is a little
different as it is at a lot slower speed (not a speed wobble) and
probably more relevant to the steering stuff you guys are talking
about. At about 35 mph the front forks got kicked left and the front
end got knocked that way too. Having not leaned into the "turn" my
front tire going left, turned left, me far right of the line of
balance of the bike and heading down fast. However, in this situation
the angle behind the area of straight force of the front tire was
becoming greater which of course forced the front forks to pivot sharp
right. Now the front end is way right of me, me still in line with my
origional angle of travel as this was all happening faster than I
could react. The process repeated a few times until I the bike was
upright again. The point here is if you turn the forks right, and do
not lean into the turn, the further over the bike leans the more it
wants to straighten the forks out on its own depending on the angle of
rake in the forks. Hope that makes sense, I am sure I used improper
terminology but I hope you all got my point. A real counter steer will
get you slapped on the turf if I am interpreting you all correctly. ;)

I'd expect the trail on your bicycle to be much less than that on your
motorcycle, and the motorcycle has much more momentum helping it lean.

Also I noted thunder's comment about the gyroscopic effect of the wheels.

A friend once improperly adjusted the rear suspension on my wife's bike.
She got it up to about 50 mph and the front end went crazy wobbling. She
let off the throttle and somehow managed to keep it under control. The
wobble left once she slowed back down. Needless to say, I put the
suspension adjustment back where it had been.

my front end sharply to the left, turning my wheel left and started to
deposit me down to the right as will happen when a front tire looses
grip on a bike. Loosening up my grip preparing to eat asphalt my front
end caught and kicked the tire around to the right, now the bike is
turning right and laying down to the left, again the tire, because of
the rake of the fork kicked to the left, kicking the bike upright and
back to the left. This wobble continued about 3-5 times until the bike
stood itself right up again. I pulled over and cleaned my pants. The
reverse lean steer saved my ass from a bad hit and it was only because
of the geometry of the bike that it happened, call it reverse steer,
call it great engineering, either way it was one time I f*****d up and
did not eat pavement..


There have been highway accidents due to "wobble" loss of control. They are
usually caused by riding too fast while navigating a long, sloping turn in
the road and suddenly de-accelerating for some reason. I've never
experienced it (hope I never will) but have been told that if it starts, hit
the throttle to maintain control and slow down more slowly.

We used to get that wobble coming in 84 east bound just west of the
mass border, I am sure SW is familiar with the old highway. And you
can not just brake to stop it, you gotta maintain throttle and come
off real slow, and real out of control. My Bike used to get it at
certain speeds, somewhere under 80 I think there was a band where it
was real bad. The wobble I described in my almost wreck is a little
different as it is at a lot slower speed (not a speed wobble) and
probably more relevant to the steering stuff you guys are talking
about. At about 35 mph the front forks got kicked left and the front
end got knocked that way too. Having not leaned into the "turn" my
front tire going left, turned left, me far right of the line of
balance of the bike and heading down fast. However, in this situation
the angle behind the area of straight force of the front tire was
becoming greater which of course forced the front forks to pivot sharp
right. Now the front end is way right of me, me still in line with my
origional angle of travel as this was all happening faster than I
could react. The process repeated a few times until I the bike was
upright again. The point here is if you turn the forks right, and do
not lean into the turn, the further over the bike leans the more it
wants to straighten the forks out on its own depending on the angle of
rake in the forks. Hope that makes sense, I am sure I used improper
terminology but I hope you all got my point. A real counter steer will
get you slapped on the turf if I am interpreting you all correctly. ;)


It sounds like your front suspension may not have been up to the curve you
were taking at the speed you were taking it. I've had a wobble show up in
curves on my Guzzi. I've since added fork bracing to the front end. The
wobble has never returned.

Countersteering is not a 'trick' or new way of steering. It's what makes
your motorcycle turn, every time you turn.

Also I noted thunder's comment about the gyroscopic effect of the
wheels. Terry Colon, in the reference JimH provided, commented on that:

"Counter-steering tilts your motorcycle into a turn faster than you can
lean it shifting your own weight by using the motorcycle's momentum to
force itself into the desired tilting angle."

and, "Some folks will tell you it's the gyroscopic effect of rotating
the front wheel tilting your bike in counter-steering. Some folks would
be wrong."
John, read for content. I didn't say anything about the gyroscopic
effect tilting your bike in counter-steering. It doesn't. It does
straighten your wheel after the lean is accomplished. If it didn't, your
wheel would continue to the right, and you would have a nice case of road
rash.


Oh, OK. Sorry I misread what you said.

You should have been around when all the name-calling was going on about
whether or not countersteering even existed!


It was so obvious that even JimH would finally figure it out JimH. It
was nice to see him do his infamous "Opps ..... Never mind" routines.


Nothing new there!

Forgot to mention this yesterday.


I have signed up for a MC riding course at Excalibur Motorsports in
Plainfield.


I intend to put this left/right controversy to rest once and for all
not out of disrespect for your opinions but because you are wrong.


Not that there is anything wrong with that. :)


And I would point out to all you heathens who actually believe that
left/right nonsense that up until ten or so years ago, it was thought
that the curveball didn't curve - it was an optical illusion.


EXCELSIOR!! :)


How would you like your crow cooked?

Looks like countersteering is the initial process in turning a bicycle as
one *has* to lean into the turn, even at slow speeds (where the lean is not
obvious).


My apologies to you and John. ;-)


BTW, I think Terry Colon is wrong, partially, in his description of bicycle
steering. Therefore, I sent him the following email:


"
Your article on countersteering was used in a usegroup as proof that it
exists. In your article, you state that countersteering isn't used much
with bicycles, because leaning the body is sufficient to get the bike
turning. (http://www.terrycolon.com/1features/bike2.html)


I disagree. I believe that leaning the body, without changing the geometry
of the arms, does initiate a countersteer which turns the bicycle. If you
lean left, and don't bend your left elbow to compensate, you will push on
the left handlebar, thus countersteering. Try riding your bicycle and
leaning while keeping the bike in a straight direction. It is very easy to
do. You'll notice that you compensate for the lean with the geometry of
your arms, ensuring that you don't countersteer.


Thanks for your articles, by the way.

Well I been kinda' busy the last few days looking for a new boat so I
have not followed this much, I do need to come in here quickly as I
have a little experience in this field having had my bike licence for
over 30 years now. I was riding one dark night back in the mid 80's,
middle of winter riding to work. I hit a huge chunk of ice/slush that
had frozen to the road, about the size of a cinder block. It knocked
my front end sharply to the left, turning my wheel left and started to
deposit me down to the right as will happen when a front tire looses

Those 'death wobbles' are bad news. I got forced off the road by a semi out
near Richland, WA. Hit a bunch of loose gravel. The wobble started, but I
had no idea, at the time, how to get out of it. So, the bike and I went
down, skidded for a looooonnng ways, and did a lot of damage to me *and*
the bike. (Like a total dumb ass, I wasn't wearing leathers or even a
shirt. Hell, I was trying to get a suntan!)- Hide quoted text -

Highspeed wobble isn't a good thing. That's one reason why the old
Kawasaki 3-cyl 2-stroke 750's were called "Widow Makers" If the
extreme wheelie caused from ripping the gears with 80 hp, and an
obnoxious powerband, up to 3rd gear didn't get you, usually the "HSW"
would. Kawasaki had a design flaw in in that bike, due to the the
center of gravity with the placement of the engine in the frame,,
pluse overall weight distribution, and fork rake etc. Just made a bad
combination all the way around.

But man what a gas to ride!

BTW, John, this obviously isn't it, but my Guzzi that got me though
college was exactly like this with enception of the Speedo and Tach
cluster, I later put a Wixom fairing on it, to keep down on the winter
cold when the weather would permit riding. and when you're a young

Very cool! I had an Eldorado for a while, but only to fix up and then sell.
They are very popular, still, with the Guzzi folks, so I was able to make a
pretty good profit on it. It's a shame you don't still have it!

The Mille GT was one of the few big bikes Guzzi made with a small, plastic
front fender. And the fender provided no bracing whatsoever. I put the
front end from an 850T on it, and the wobble problem went away.

The site you discovered was from Teo Lamer's shop in the Netherlands. Teo
is the one who loaned me a bike a couple years ago for a trip we took down
to the Cote d'Azur and back up through the French Alps. What a coincidence
that you should get his site! He's the biggest Guzzi dealer in the
Netherlands, and one of the biggest in Europe.- Hide quoted text -

Cool that you got a bike from him for your tour. Interesting to note,
that riders in Italy will actually order a bike through him and pay
all he duties, and shipping to get it back to Italy, Because he has
them when nobody else does, like he's the first in line.

the reason my Tach and Speedo cluster was different, is because when I
got the bike somebody had vandalized it at a bar, and took a tire iron
to them. amazing that was the only damage done, but the guy got hauled
off before he could do worse. Anyhow, I found a speedometer mount from
a '68 V-7, so my Guzzzi, was almost all Eldo, with a little bit of
Ambassador thrown on top.

Makes one wonder what they were thinking, doesn't it?

You're Mille, didn't still have the backward shifting did it?
