The Bad Side - Lefts Or Rights?
fear of making left or right turns
There are technical points concerning a rider's fear of making either right or left hand turns. Many riders have this fear and it's frustrating. Scores of riders have complained to me about this with a sheepish sort of approach and "admitted" they were perplexed by it. Rightfully so, roughly 50% of their turns were being hampered by an unknown, un-categorized, seemingly unapproachable fear having no apparent source and no apparent reasoning behind it. Out of desperation for an answer riders have blamed their inability on being right or left handed, mysterious brain malfunctions and a host of other equally dead end "nonsense solutions"; nonsense because none of them answered their questions or addressed the hesitance, uncertainty and fear. Having a fear of right turns would be the worst if you lived in Kansas or Nebraska where practically the only turns worth the title are freeway on and off ramps. If you went "ramping" with your friends, "doing the cloverleaf", round and round, you'd be at the back of the pack . Anxiety on lefts would exclude you from the dirt track racing business for sure but mainly we are talking about day to day riding and any such apprehension as this (and there are others) spoils a rider's confidence, making him somewhat gun shy. There are actually three reasons why you could have this unidirectional phobia (fear) and all three contain an inordinate amount of some emotional response that runs from suspicion and distrust to mild panic and a dose of plain old anxiety dropped into the middle for good measure. By the way, if you consider yourself in this category of rider, count your blessings, many riders have bidirectional phobia and it's only by their force of will and love of freedom that they persist in their riding at all!
First Reason
Reason number one for this fear is that you crashed on the right or left at sometime and the relatively indelible mental scar is still on the mend but remains a more or less hidden and nagging source of irritation. The part of the mind that is concerned with survival does not easily forget and the proof is that our species still exists.
There have no doubt been other more pressing problems along the way that have tried and tested Man in his effort to put order into his environment. The fact that the incident of a crash drops down to an obscure sub-level of awareness is not a help in this, or perhaps any other case, as it can affect our riding from there and can add an unpredictable element to our riding.
You may gain some control over this with practice but the oddest part of it is that if one hasn't ridden for a while this apprehension of turning right or left can return in force... provided it springs from this particular source. In the technology of the mind and according to the discipline of Dianetics, these incidents are stored in what is called the Reactive Mind, for the obvious reason that one finds himself reacting to, rather than being coactive with, some circumstance. In this case, right or left turns.
Second Reason
In the discipline of riding technology we have the act and activity of counter-steering to contend with. Here a rider may have become confused, in a panic of some sort, and gone back to another variety of "survival response" that pressed him into turning the bike's bars in the direction he wanted to go rather than doing the correct (and backwards from other vehicle's steering) action of counter-steering. That instant of confusion has stopped many riders cold in their tracks, never to twist their wrist again and pleasure themselves with motorcycle riding.
Turn left to go right push the right bar to go right, its the thing that eludes us in that panic situation (statistically) more commonly than anything save only the overuse and locking of the rear brake.
When you dissect this confusion regarding the counter-steering process you see that it is possibly more devastating than the rear end lock up, even though both have the same result, the bike goes straight, and often straight into that which we were trying to avoid. Basics prevail--You can only do two things on a motorcycle, change its speed and change its direction. Confusion on counter-steering locks up the individual's senses tighter than a transmission run without oil and reduces those two necessary control factors down to one...A bad deal in anyone's book.
Third Reason
The third possible reason for being irrational about rights and lefts is the one that has solved it more often than not--practice. Applying the drill sergeant's viewpoint of repeatedly training the rider to practice and eventually master the maneuver is a very practical solution. I suppose this one falls under the heading of the discipline of rider dynamics. And a casual inspection of riders will show you the following: Ninety-five percent of all riders push the bike down and away from their body to initiate a turn or steering action, especially when attempting to do it rapidly. Rapidly meaning something on the order of how fast you would have to turn your bike if someone stopped quickly in front of you and you wanted to simply ride around them; or avoid a pothole or a rock or any obstacle.
For example, a muffler falls off the car in front on the freeway at 60 m.p.h., that's eighty-eight feet per second of headway you are making down the road. Despite the fact you've left a generous forty feet between you and the car, that translates into one half second to get the bike's direction diverted, including your reaction time to begin the steering process. We're talking about a couple of tenths of a second here--right now.
This procedure riders have of pushing the bike down and away from themselves to steer it seems like an automatic response and is most probably an attempt to keep oneself in the normally correct relationship to the planet and its gravity, namely, vertically oriented or perpendicular to the ground. This is a good idea for walking, sitting and standing--but not for riding. When you stay "on top" of the bike, pushing it under and away, you actually commit a number of riding dynamics sins. The first of which is the bad passenger syndrome."
Bad Passenger
Bad passengers lean the wrong way on the bike. They position themselves in perfect discord--counter to your intended lean, steering and cornering sensibilities. So do you when you push the bike away from yourself, or hold your body rigidly upright on the bike--very stately looking, very cool but ultimately it's an inefficient rider position. The most usual solution to a bad passenger's efforts to go against the bike's cornering lean angle is brow beating them and threaten "no more rides." But how do you fix this tendency in yourself?
A bad passenger makes you correct your steering and eventually become wary of their actions and the bike's response to them. This ultimately leads to becoming tense on the bike while in turns. Pushing the bike away from yourself or sitting rigidly upright while riding solo has the same effect.
Hung Off Upright
Hang off style riders don't think this applies to them but it does. Many riders are still pushing the bike under themselves while hung off. Look through some race photos especially on the club and national level and you will easily see that some are still trying to be bad passengers on their own bike and countering the benefits of the hung position by trying to remain upright through the corners.
A rider's hung-off style may have more to do with his ability to be comfortable with the lean of the bike, and go with it, than anything else. This is not to say there is only one way to sit on a bike, in any style of riding. But it does mean that each rider must find his own way of agreeing with his bike's dynamics and remain in good perspective to the road. And this doesn't mean that you always have to have your head and eyes parallel with the horizon as some riders claim. But it does mean that you may have to push yourself to get out of the "man is an upright beast" mode of thinking and ride with the bike, not against it. It may feel awkward at first but it's the only way to be "in-unit" with the bike. On a professional level most riders do this. John Kocinski is an example of someone in perfect harmony with his machine and Mick Doohan has modified his sit-up push-it-under style of riding over the past couple of years to one that is more in line with the bike.
Show and Tell
If you have a rider (or yourself) do a quick flick, side to side, steering maneuver in a parking lot you'll clearly observe them jerking and stuffing the bike underneath themselves in an effort to overwhelm it with good intentions and brute force rather than using correct, effective and efficient steering technique.
There are other steering quirks you may observe while having someone do this simple show-and-tell parking lot drills. For example, some riders have a sudden hitch that comes at the end of the steering when they have leaned it over as far as they dare. It's a kind of jerking motion initiated from their rigid upper body.
You may see an exaggerated movement at the hips; that's another variation of their attempt to keep the back erect. Also, look for no movement of the head or extreme movement of it to keep the head erect. A general tenseness of the whole body is common as is lots of side to side motion of the bike. So what's the right thing to do here?
Good Passenger
What does a good passenger do? NOTHING. They just sit there and enjoy the ride, practically limp on the saddle. The bike leans over and so does the passenger. Which scenario agrees with motorcycle design: weight on top that is moving or weight that is stable and tracking with it? Motorcycles respond best to a positive and sure hand that does the least amount of changing. You, as a rider, need to do the same thing, basically, NOTHING. Holding your body upright is not doing nothing it is doing something. It is an action you initiate, a tenseness you provide and it is in opposition to the bike's intended design--what it likes.
More Lean
There is another technical point here. The more you stay erect and try to push the bike down and away (motocross style riding) the more leaned over you must be to get through the turn. That's a fact. Crotch rocket jockeys hang off their bikes for show but the pros do it to lean their bikes over less. You can counter this adverse affect of having to lean more by simply going with the bike while you turn it, in concert with and congruous to its motion, not against it. There is even an outside chance you may find it feels better and improves your control over the bike and reduces the number of mini-actions needed to corner. There is also a good possibility that this will open the door to conquering your directional fear, whichever form it may take.
Diagnosis
Look for one or more of these indications on your "bad" side:
1. The body is stiff or tense while making turns on the side you don't like, at least more so than on the side you do like.
2. You don't allow your body to go with the bike's lean on side: You are fighting it and it is fighting you.
3. The effort to remain perfectly vertical is greater on your bad side.
4. You will find yourself being less aggressive with the turning process on your bad side.
5. You will find yourself being shortsighted, looking too close to the bike on that shy side.
6. You will find yourself making more steering corrections by trying to "dip" the bike into turns or pressing and releasing the bars several times in each turn.
7. You will notice a tendency to stiff arm the steering.
8. You will notice you are trying to steer the bike with your shoulders rather than you arms.
You might find more symptoms but one or more of the above will be present on your bad side.
Coaching
The very best and simplest way I've found to cure this tendency to push the bike under is to have someone watch you while you do a quick flick, back and forth, steering drill in a parking lot. You have your friend stand at one point and you ride directly away from him or her as though you were weaving cones and then turn around and ride directly back at them weaving as quickly as you feel comfortable and at a speed you like, usually second gear. In that way your coach is able to see you either going with the bike at each steering change or they will see you and the bike crisscrossing back and forth from each other.
As the coach, that's what you are looking for, the bike and the rider doing the same action, the rider's body is leaned over the same as the bike at each and every point from beginning of the steering action to the end. There is no trick to seeing this...it is obvious. For example, when they ride away from you, if you see the mirrors moving closer and further away from the rider's body, they are obviously not moving together. That's pushing the bike under rather than good steering. This is also the time to notice which side is the rider's bad side. The back and forth flicks will be hesitant on one side or the other.
Remedies
The entire purpose of this exercise is to have the rider get in better communication with his machine--going with it not against it--and not treating it as though it were a foreign object that he is wrestling to stay on top of or muscle it down like a rodeo rider. Often, it simply takes a reminder to loosen-up the upper body. Sometimes the rider needs to lean forward and imagine the tank and he are one and the same. On sportbikes, a full crouch over the tank can sometimes be the answer to link the rider with his bike, giving him a ready reference to it's physical attitude in relation to the road.
Making sure the rider has some bend in his elbows while leaning forward slightly seems to help. Having them use palm pressure to steer the bike seems to resolve the tendency to muscle the bike over from side to side. Dropping the elbows so the forearm is more level with the tank makes the steering easier and promotes their going with the bike and takes them away from the stiff armed approach to steering. Reminders to relax the shoulders and let the arms do the work of steering also helps.
End Result
You stop doing the drill when the rider has the feeling he is in better control of the bike, when he has the idea of how easy and how much less effort it takes to steer; or when he feels comfortable with both rights and lefts. There could be other contributing factors like overly worn tires or a bent frame that would bring a genuine and justified anxiety to a right or left turn but I believe the above three reasons cover everything else and if you are anything like the hundreds of riders I've had do the above drill, you could use a little work on this area even if you don't have a bad side. I hope it helps.

Brake/Down-"Changing Gears Like a Pro"
Changing Gears Like a Pro
Barriers Open Doors
To make real improvement there must first exist a real barrier to overcome or a real result to achieve. These are always based on the rider?s own desires: to go faster; be more in control; have fewer panic situations; put it all together into a smooth flow or simply remove doubts and questions they have relating to those goals: when do the tires slide, how hard can I brake, how far can I lean the bike and so on.
When you look at it you?ll see that there is very little difference, if any, between a riding barrier and a riding goal; they both have the same stumbling blocks. They both have an end result to achieve. They both have some fear or uncertainty or distraction attached to them. There is always a barrier.
The Braking & Downshifting Barrier
An example of a common barrier would be the complications that arise from the hurried and slightly frantic control operations that stem from not learning to smoothly and simultaneously brake and downshift for traffic lights, obstructions and, of course, corners.
Doesn?t sound like a life or death threatening situation but when inspected closely you see what impact it really has on a rider?s attention and how they are spending it.
Check it out, if the rider can?t do braking and downshifting, simultaneously and smoothly, they are forced into one or more of the following attention draining scenarios:
1. Slowly letting out the clutch to make the downshift smoothly. This requires attention to be spent and is the most common way uneducated riders handle it.
2. Having to change gears once the bike is stopped. When the bike is stopped even the best transmissions can be sticky. Gears change more easily and more positively when the bike is moving. It causes less wear on the gearbox to change the gears while you are moving.
3. Having to change the gears after the braking is completed for a turn. That means doing it in the curve. This is distracting and can upset the bike, to say nothing of the rider.
4. Alternately going from the brake to the gas to match revs for the downshifts. This has the bike pogoing at the front. It does not get the bike slowed down quickly in an efficient manner. This is very busy riding.
5. Downshift before braking. This is fine for very relaxed riding situations at slow speeds but is hazardous to the engine if the rider is in ?spirited cornering? mode as it provides the opportunity to over-rev the motor and bypass the rev limiter that protects it. Could be very expensive. In an emergency situation you don?t have time to do this because you should be on the brakes right away. Not only that but some emergencies require you to brake and then get on the gas right away for accelerating hard to avoid things like cars running a light on you. In this case the rider would not have the time to get it done.
6. Forget it entirely and just go through the corner. This forces downshift(s) to be done at the corner?s exit thus losing the drive out and complicating the whole thing by having to make a gear change when they should be rolling on the throttle. This is distracting and not smooth at all.
Coordination And Concentration
It is true that if a rider was uncoordinated and attempts simultaneous braking and downshifting it could be dangerous. For example having the front brake on along with the power can make your front wheel lock up.
On our panic-stop training bike I have seen it many times: the rider aggressively squeezes the brake and unconsciously rolls the throttle on at the same time. It?s spooky to watch. So yes, practice and coordination are necessary, you will have to practice.
More importantly, you have to make a decision. Are the 6 potential distractions above likely to get you into trouble? They do break the rider?s concentration even if only slightly. In other words: if you aren?t a super hero at multitasking each of the 6 is a negative in comparison with braking and downshifting simultaneously.
In Control = In Communication
Continuous perception of your speed is how you control it. Accurate turn entry speed is critical to good, confident cornering. If you are worried about your speed, you are distracted by it.
Finding the right turn entry speed (for you) is far easier when the braking and downshifting are happening in one continuous flow of change. When compared to one that is chopped up, incomplete or creates anxiety like having to shift in the turn, it?s obvious which scenario is better. Your Sense of Speed is a precious resource and is far more accurate when monitored as a steady stream with your awareness.
Maintaining a continuous state of awareness of what the bike itself is doing is another of the true benefits of this technique. You always know where the engine speed is in relation to the road speed and that improves your feel for the bike.
Your communication with the machine improves; no false signals or guess work; no waiting to know how the bike will respond in any of the above scenarios. You ability to maintain communication with the bike is important input.
Naming It
Simultaneous braking and downshifting. I?d like to shorten it to something like brake-down. Car guys call it heel and toe, which is a nice, short and simple way of saying they are simultaneously using the brake pedal with their toe and revving the motor with their heel. In some cars you just put the ball of your foot between the brake and gas pedals and rock your foot side to side to do it, it depends on the pedal arrangement. On a bike, provided the brake lever is comfortably adjusted to fit your hand, they are always in the same position for our maneuver.
Alright, for now it is brake-down. It would be interesting to have a non rider hear about you executing a ?breakdown? coming into a curve; sounds pretty dangerous. How about fist and fingers or palm and fingers or B&Ding, ?
Whatever we call it, it works to simplify corner entries and puts the rider in command of and in communication with his machine to the highest possible degree.
The Sequence
1. Gas goes off.
2. Brake goes on.
3. Bike slows some.
4. Clutch comes in.
Maintain brake lever pressure.
5. Blip the gas rapidly on and off. (Usually no more than a quarter turn).
Maintain brake lever pressure.
6. During the blip make the gear change positively and quickly.
Maintain brake lever pressure.
7. Clutch comes out.
Maintain brake lever pressure until desired turn entry speed is achieved.
8. Release brake smoothly.
Bear this in mind: the quicker you do steps #1 through #7 the better.
Brake Lever Control
Expert use of the brake during this entire cycle means that you can maintain, increase or decrease the pressure as desired, without abruptly stabbing or releasing the brake lever.
Number of Fingers
Some riders let their finger(s) slide over the brake lever as they blip the gas. Others grab the brake lever with the tips of their finger(s) and still get a continuous lever pressure without the bike pogoing up and down.
Whichever way you do it is fine. How many fingers you use for the brake is up to you: one, two, three or four, this is your choice although I recommend you try just two fingers, your index and middle ones.
What's Important ?
Braking is important, it is life and death on the street and vital on the track. Changing gears is not. You can still make it through the corner or get the bike stopped without ever touching the gears. But, riders do have the six above scenarios to contend with if they can?t do the fist/finger, down-brake, palm/finger, B&Ding technique.
Learning How
The fact that riders have a problem doing this technique led me to a solution. I?ve built a bike that trains it. We call it the Control Trainer. It takes you through the technique, step by step.
The trainer?s computer program talks you through the whole sequence and it points out your problems and how to correct them. The computer is hooked up on a static ZX9, you can?t ride it but you do get the coordination/muscle memory necessary to do it for real.
Each of the controls is monitored for: correct sequence; correct timing of the clutch and gear changes; correctly sized throttle blips and consistent brake pressure, throughout the whole process.
With or without my Control Trainer, anyone can learn to do it. Start now.

You and Valentino Rossi
It's not often we are treated to the kind of excitement that Moto GP racing is providing us with today and we see a huge difference in what he can do compared to the other riders out there on the circuit.
With Val Rossi we know that the equipment makes little or no difference, he has won on slower and less developed bikes; he breaks lap records on the last lap when everyone else complains about their tires going off and he has the same rubber as them. He's not noted, like some top racers, to maintain any sort of rigorous physical training regimen. What's up with that?
I suppose we'd all like to be able to ride like Valentino Rossi. We admire him and then we ride and can't figure out how a Human could be in such command of so many aspects of riding when we are essentially doing the same thing on the bike as he is. You work the same controls that change the speed and direction of your bike as he does.
So if it isn't the bike then it must be the man. And if it is the man it is the mind that guides it. If it is the mind that guides it, then the fuel for the mind is the perceptions of the individual rider himself that rules.
When we look over the number of perceptions that we can have it is actually pretty staggering. We perceive, line, lean angle, traction, speed and the timing and degree of control application to put them all in some kind of sensible order for ourselves.
There is the difference?what is a sensible order? When you pull on the brakes in a set of esses and someone else is wide open and upshifting you start to get some inkling of the difference between your perceptions. Leading the way on perception is our ability to process visual data. Or, more accurately, our sense of location in space.
It is easy to see that location rules when it comes to working the controls. What one rider sees is vastly different than another, even though the things that are available to use as reference points are exactly the same.
One rider's line is different than another's. How much different? Well, you might have a track that is 4 DOT lanes wide but the actual usable space for speed and control narrows down quite a bit from there. The amount of that space that you can use is limited, maybe 10 feet of it would be the amount of variance from one rider to another, maybe. That would be a generous estimate, it is probably more like 5 feet. Unless you are Valentino who seems to be able to make any line work.
What's all the fuss about lines? Big fuss. When you break it down the only logical explanation is that a rider can choose and run any line that he can see. The corollary (an easily drawn conclusion) to that is, if you can't see the line you can't choose it and you can't run it.
I can't count the number of times we've shown a rider a line and then followed him to see how good his "monkey-see-monkey-do" skills were only to find his line varied only slightly from what he had been doing and markedly varied from what we demonstrated.
What someone uses for Reference Points (RPs) and how they use them is the key. This was my first real discovery on riding back in 1976. It changed my riding and everyone that I worked with made huge leaps in their own skills by simply becoming aware of this simple fact.
What I now know is: there ARE other points that must be cemented in for a rider to have a solid enough foundation to even get to the point they can find and use good RPs with certainty and with confidence. When we take up Reference Points, and the other visual skills, on Level 2 we get to the real core of riding and it isn't that easy to master it.
So what about Valentino? Our Australian school director, Steve Brouggy, has a great way of putting it. "If you could record what you see and record what Valentino sees you would have two totally different movies." I agree.
As I have seen with lots of top riders, their biggest ongoing breakthroughs come in their ability to use their visual abilities, their perception of location. Why can a rider go through a turn 300 times and all of a sudden have a massive breakthrough and finally "understand" the turn? It happens all the time. I hope it has happened to you. If it hasn't then I know why.
Valentino does it on the fly and it seems that he has honed this ability to its finest possible point. You can see it if you look closely. Watch his lines and see not only that he can use any line in a pinch but that the differences in his and the others out there really is different.
Have fun watching for this. Truly, if you have difficulty seeing this from the camera's perspective you would have a very difficult time doing it on your own. What I'm saying is this: it's good practice to notice lines, your own and someone else's, it may give you a new idea on how to use your own eyes. Once you become interested in your lines, I hope to see you for Level 2 and sort it out.

COUNTER STEERING - by Keith Code
COUNTER STEERING - by Keith Code
The No BS (Body Steering) Machine... Thats 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 countersteer. 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 moment (to me) 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 countersteering 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 countersteering. Vague Technique Riders have a number of ideas, which are vague and hard for them to describe, on just how their weight shifting accomplishs 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 countersteering 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 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 confidence.
I decided to make 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 Bostrom 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 ..... 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 countersteering. 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.
Machine 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 Body Steering.
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 countersteering of course. At 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.
The best result was one of my instructors. He got into a full hangoff 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 very 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 countersteering 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 BS. Dangerous Misconceptions
Now if you want to look a little further into this, what you will see is this; riders who still labour 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 to the steering procedure at 60 mph means that you have just gone another 18 to 44 feet 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 COUNTERSTEERING DO NOT RIDE. SEEK THE HELP OF A QUALIFIED PROFESSIONAL INSTRUCTOR!
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 BS.
