id like to address this "no bs bike" juliet loves so much. i understand that this bike can not turn there for leaning into would do nothing for it and that once in a turn you go back to a neutral bar possition. the bike is turning (front wheel dif angle than straight rear) but dont u think if that wheel was allowed just some play and the handle bars were stationary(like #2 on a bicycle built for two) wouldnt that let the bike to be leaned into a turn? as it would take that given Xinches to follow threw the turn. its been a very long day so i dont know if i am asking correctly but i had to get if off my chest b4 bed.
but im getting this from the good old days of riding bicycles with friends and being a "cool guy" and riding with no hands and wed go for miles around turns and everything no hands so there was no way of counter steering. granted we were not going fast but physics should still work the same smaller tire less speed = more speed larger tire?(not sure if this is true but thats my thought process) also being riden on the back of a bicycle either on the seat or on pegs on the back wheel i could steer from there too just lean. i also agree with as you lean you automatically shorten and lengthen your arm which would make you counter steer making it seem like leaning is what u neeed to do.
The No B.S. Machine is a normal sport bike with an extra set grips mounted forward from the stock grips that are stationary. As you can see in the pic on this page:
http://www.superbikeschool.com/machi...bs-machine.php

The front forks are not stationary, if they were then the motorcycle would not turn at all, although it might fall over at low speeds

All of your questions are addressed on that page, but the short answer is Counter Steering is the only way to turn a motorcycle. Shifting your body weight will steer the motorcycle slightly, because the change in the center of gravity indirectly applies force on the wheel, but the effects are minimal.

You can do you very own No B.S. Machine experiment. Simply speed up to about 40 mph find a stationary part of the motorcycle to hold on to with both hands and attempt to turn the bike by leaning. Please don't experiment on public roads or parking lots. Find a private lot that is free of obstacles.

ok so the only real thing that go tfrom that is that depending on size shape of bike and tires u CAN use weight. dont get me wrong i understand how cs works ive tried and its deffinetly there but what i dont understand is the "SHIFTING WEIGHT DOESNT TURN" statements.

and on the bs bike i guess i was a little off but with the front wheel being able to move than why wouldnt my therory work? again i ride my scooter NO HANDS not on the tank or stationary part but none what so ever and i can change lanes and take broad turns. im not trying to disagree with CS but i just would like more insight on the fact that people keep saying weight change does NOT turn. a few spots its been said that CS is the best most efficiant for a quick manuver which would lead me to belive that a slow inefficiant way is out there ie leaning. and weeeezzll you say "Counter Steering is the only way to turn a motorcycle. Shifting your body weight will steer the motorcycle slightly" now am i just getting caught up in samantics? are you saying that turn and steer are not the same. by a tecnical dictionary definition i understand that but wen talkin about making a bike move to me they are the same maybe im just getting caught up in the word play of it

"Countersteering is required to turn any tandem 2-wheeled vehicle. Most people are not consciously aware that they employ countersteering when riding their bike any more than they are aware of the physics of walking. They have learned to subconsciously apply the required countersteering."

To answer your question about leaning:
"It is often claimed that two-wheeled vehicles can be steered using only weight shifts. While this is true for small "trim" inputs to direction, complex maneuvers are not possible using weightshifting alone because even for a light machine there is insufficient control authority."

When people say "learning to countersteer" what they really mean is "learning to consciously countersteer"

For the nitty-gritty details see: http://en.wikipedia.org/wiki/Countersteering

ok so i guess i may have been getting cought up in terms and such.(but why call it counter steering wen thats HOW you have to steer. yes you do the opposite of a car but ur still turning some forward moving thing. now a fork lift where you steer with rear wheel and go forward and backwards i see counter being used there. but what ever.) but that was a good read and my no hands thing was explained and there was something else going on that i was unaware of iw as just a little backwards on how to look at it.

now ive read forums and talked to racers. and from what i know i thought you only countersteered when going slow but when going faster. you literally lean your body off of the bike and your head to the outside mirror. am i wrong? or are there more than just one technique to get the max grip on the front tire?

Hanging your body off the bike changes the bike's center of gravity. That change will allow you to make the same turn with less lean angle than if you sat straight up in the saddle. But countersteering, especially at higher speeds, is what initiates the lean. And the lean is what makes the bike turn.

Some of you are getting confused obver the whole lean thing versus counter steering ... the reason you can often turn a cycle or a light scooter by leaning is because they are so light in comparison to your body weight ... take for instance a cycle, hold it upright by the seat and lean it toward you or away from you and you will observe the steering falls to whatever side you lean it to, now take your light scooter at low speeds and a similar thing happens ...


The NO BS bike though is a whole different ball game, it's a proper sized motorbike with mass and when travelling along at say 50mph has serious momentum ... if you let go of the bars and try to turn it by leaning you will get little to no turn from it, the steering won't fall to the side you try to lean it because the gyroscopic force of the front wheel tends to keep it stable, that is why it is easy to let go of the bars at speed on a bike ... the wheels acting as a gyroscope keeps the bike upright, witness a racer falling off his bike and the bike carrying on upright with no rider,

So with a full size motorcycle moving at speed, say 50-60mph the only effective way to make that machine turn fast from left to right down windy country lanes is via counter steering and this means input through the handlebars, leaning off is a different matter as mentioned above it is done to change the bike's C of G and let's you keep the bike more upright through a turn, all of this is fact and not an opinion ... go back and read about the No BS bike, everyone doubter who rides it becomes a total believer once they have experienced it for themselves.

Also .. when you lean off to the left there is a natural tendency to shorten your right arm and pull the right bar at the same time pushing the left bar ..you just dont notice this and think you turned by leaning, you didnt, you counter steered ...


It is Counter Steering, and *that* alone that will save your life in an emergency of obstacle avoidance ...

..and here it is again to save going back to find it, the No B.S bike ... click on the link and read all about it


http://www.superbikeschool.com/machi...bs-machine.php


I think this bit is important :-) ..


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 countersteering 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 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 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.


I really like this bit and I do think they should carry labels because it is simply so scary how many people are not aware of counter steering or only do it subconsciously ... you simply have to consciously be able to counter steer in an emergency ... it's a life saver!!



WARNING: THIS VEHICLE COUNTER-STEERS.
IF YOU DO NOT UNDERSTAND COUNTERSTEERING DO NOT RIDE.
