The Physics of Countersteering

[@yxngfauzthesaucegod7427]

i won't be the first to say this and certainly not the last but this is the first video that made sense after like 10 videos

[@Z4G.]

I didnt get how countersteering worked. But after i got my first bike, i realized how it worked. Very hard to understand from an explanation, but very easy to understand when doing it

[@warchitect73]

gotta check out "twist of the wrist" videos. really good on this. and other stuff.

[@dinhdatVN]

I second this.

[@ciguana2mlgprovideo388]

I your going right lean right if your going left lean left just make sure you don't lean to much

[@decidiousrex]

Seriously. It's very mildly complicated physics, but hop on a bike, get to speed, and try turning the handlebars. You go the opposite way you intend. It's that basic.

[@shuumai]

The description at 2:32 was critical for me. Counter-steer then LET the bike turn. Relaxing on the bars allows the bike to naturally "fall" into the turn.

[@enematwatson1357]

shuumai Quite. A point that is amazingly difficult to convey effectively.

[@steve24822]

It is really important to release the counter steer to get the maximum steer in the direction you want. This is after us8ng counter steer to get you into the desired lean angle. Unfortunately this video only tells half the story which is why it is so simple to understand. I was going to make a digital protractor attached to a bike so we could see the actual amount of steer and in which direction throughout a turn to finally put this subject to bed. I am amazed that no one has done it yet.

[@mildyproductive9726]

@@steve24822 It depends on the bike, though. If the bike has a taller center of gravity and less aggressive steering geometry, it is as you say. You countertweak the bar, momentarily, then you relax (or even help whip the bars into the turn if you did a super aggro counter tweak), then once on your arc/radius, you generally have to reapply and hold a bit of counter force to maintain that arc under any bit of throttle. But on the more modern super sport crotch rockets, the steering can be so quick that you never have to "let go" of the countersteer. The bike instantly rolls and achieves a new equilibrium throughout the entire process. It's all happening at once. As soon as you start to apply counterpressure, the bike instantly leans and changes arc (taking the fork with it, into the turn) and you continue this continual process degree by degree (very rapidly, mind you) until you reach the radius you want. Instead of dialing in one big bite at a time, you are ordering and eating and digesting tiny nibbles of your turn, a la carte, until you're there... cuz it happens that fast. On this quick-steering crotch rocket, the only time you will feel any separation between the different parts of the process is maybe in a very tight switchback at around 30 mph. Depending on your motorcycle's geometry, you can have a very different experience from another rider. This super quick steering doesn't mean the bike can turn any harder or tighter or go any faster. Or avoid a pothole any better. But is does allow for a bit more gradual and continous course corrections mid-turn and is generally regarded as enabling potentially better lap times. It is no fun to ride, though. Distinctly feeling the different parts of the turn is very rewarding.

[@Gau-Chuu]

kzbin.info/www/bejne/pZWte4uenJxsoJo this video right here is long but it’s the only video you will ever have to watch to teach you how to ride. It’s older and corny but the facts and knowledge involved is amazing I always refer back to this video and watch sections of it all the time after rides because you have to build that muscle memory and perfect all these basic skills and I guess advanced as well but perfecting the skills taught in this video will make you an amazing rider if you take the time to actually properly learn and practice this stuff. Anyone can become a good rider practicing bad habits. Make sure you are practicing the right thing and you will be amazed on how good will become.

[@Gau-Chuu]

[@Shazzkid]

Its weird that most riders do this intuitively without ever knowing they're doing it

[@juanpinate7319]

Yeah xD

[@smythe7480]

So is it like riding a bicycle when you go thru corners?

[@wriches]

Surely it's all riders that do this rather than most? It's the standard way to turn isn't it? Even if you don't know you're doing it. The only other ways to turn are to to just turn the bars in the direction you wanna go, but that only works at very low speed. Or to lean bike without initiating countersteering first, which is more advanced and more for racing, trials etc.

[@vking5665]

Most motorcycle fatalities are New Riders who instinctively think by turning away from the object they are trying to avoid will move them away. Which actually sends them toward it. So not every rider does it in a panic situation. The last thing that enters a Rookies mind is aim for what I’m trying to avoid to get away from it.

[@dwayne4887]

This is by far the BEST explanation ever!! All everyone ever says is to turn in the opposite way that you want to go, and that just did not make sense to me. What this has explained is that turning your wheel in the opposite direction "is only a momentary event" to get the bike to lean. Once you are in the turn your wheel is no longer being turned away, it's now following that path of the direction you are going, please do not overlook that part of what was said. Bravo .. I now get it.

[@Lehmann108]

Yes, it is the lean created by the centripetal force of the counter-steer the turns you in that direction. This is why if you start a turn by a hard lean followed by turning in that direction there is no counter steer effect. Counter-steer is most powerful when you are completely upright. It is the only way to avoid suddenly appearing obstacles.

[@Ducati_Dude]

Dwayne Washington --> You are Wrong Sir... When you are in a turn/corner, the rider Must 'maintain' that push on the grip (wheel turned slightly in the opposite direction) to keep the bike in the lean... if you let up pushing on the grip, the gyroscopic effect of the spinning wheels will then pull the bike upright. Not good in the middle of a turn...

[@SeraphinoII]

You are partially right Ducati dude. The thing is if you are in a corner you can just lean with your body in the corner and make your weight to create the counter steer you need without pressing the handlebar. Of course if you have to tighten the corner just press on the inside handlebar some more and adjust your position accordingly .

[@omega5040]

Your tire is still turned the opposite direction lightly while leaning towards the turn.

[@ziptimeandspace]

@@Ducati_Dude I guess you have a bike, so try your experiment; Don't blame me when you crash. Sorry, I don't mean that!. Honestly though I can go around a a corner (say a slip road to a motorway) and once at a set lean angle can take my hands off the bars (ok, assume const. throttle) and maintain a constant radius - no steering input needed.

[@ElanTanzer]

Wow, when I had created this video 6 years with my ex-husband in our living room as we were coming up with the initial concept of the Cambridge Science Centre, I never expected it to be so widely received and appreciated.

This shows how a MC turns without ANY countersteering. It also shows the continious torque (pressing) is required while turning. When torque is removed, the MC automaically returns to vertical straight line travel. kzbin.info/www/bejne/Z5qwnGyNlrqBZrc

I've watched so many videos about counter steering trying to understand it and, unlike the other videos, this actually makes sense. All of the other videos just said, "oh it sounds but backwards but this is how it works trust me just do it," and they barely even explained how to do it. It's just a 2-3 minute video saying, "turn it left and it goes right"

[@dinhdatVN]

i second this.

[@PhilWollerman]

Here's an easy way to get you head around it. Get hold of a bicycle and walk it along steering only by holding the seat - you've probably already done this. To get it to turn, you exaggerate the lean until the handlebars flop down to the right position. You might be a bit naughty and ride your motorcycle with you hands of the bars using the same technique to steer. Countersteering is doing the same thing to the bars but by pushing.

[@cardiacpa]

Basic Weeb It is easier to understand like this for me. "Push right, go right. Push left go left". Then it is not opposite or counterintuitive. It is what I have been doing for years, but I didn't know I was doing it until I saw one of these videos. I wasn't sure I was doing it until I practiced it and it did exactly what I expected and I did it at speed and it felt natural. It is the only way to make turns at speed for me. It only takes a small push to get the bike to lean, but the harder the push, the tighter and more the lean you get. If you want a tight 'Laguna Seca' turn you push hard and slow, and get the knee out to take the turn.

[@WiseWik]

Phil Wollerman umm, no. Try again Phil.

You were going great until 2:12 - it is gyroscopic procession that causes the front wheel to lean and it is the gyroscopic force working with frame geometry and frame integrity that cause the rear of the bike to follow and thus steer the bike.

Still the BEST coutersteering explanation in existence. Concise, comprehensive, clear... perfect!

[@jonnydarke]

On my bike training years ago my instructor (Ex RAF, superb bloke) took me on a straight road and told me to "Gently" push on the right and then the left handlebar while he explained the principle through my earpiece. It was a good introduction method weaving opposite to my inputs down the road, then he took me through the corners to slowly build my confidence. We do it without thinking on a pushbike but as the weight is so low we don't notice we are doing it. Great video, it was a very good example to show my son who's getting ready for his first bike. Happy riding folks!

[@vyjk]

There are probably as many Countersteering videos as there are moto-vloggers/youtubers with motorcycles. Most of those videos are more... practical in nature- guy/girl on a bike showing how it's done. This video explains the physics of it the best. To a lot of people motorcycling is about being part of and feeling the world around them. I think knowing how it all works adds to the experience measurably. Thank you for the video.

After many confusing videos about countersteering, particularly from the video with the guy who kept saying "i'm not a science rocket", I'm so relieved to have found this video!

[@wmgthilgen]

Counter steering becomes a natural process with experience. Only by practicing, can one learn the muscle memory required in cornering a bike properly on any turn at high or liw speed. That's the problem, the vast number of of bike owners, don't ride often enough to warrent the practice they need to establish previous let alone the new muscle memory required in any turning conditions they may face. On average, a new bike owners will buy a bike, opt in on a group ride and while riding two up, attempt to keep up to vetern riders. A very bad idea. I was an avid rider in my youth, got involved with raising a family and quit for 20 years. Although I had hundreds of hours and thousands of mikes of riding experience in the past, under my belt. My first ride home from the dealer, frightened me the most. The muscle memory required in turning regardless of speed and or conditions was all but gone. It took longer than I would like to admit riding like a complete newbie on lonely curvy roads and empty parking lots at slow speeds before my regaining the muscle memory I once had.

[@sleepyjessie]

William Guy Thilgen Jr. I think because of how fun the whole experience of riding is (especially for a new rider) it's easy to forget how much time we spent practicing when we first started. I've been riding two years now and just got my full unrestricted license (UK) so we were itching to get my girlfriend on pillion and go on a ride together. On our first ride we only went around the estate (or block), but we spent ages doing it, getting used to how it handles (and for her, learning how to ride pillion and getting comfortable with it). Only then did I remember how many countless hours I'd spent in the saddle before being confident and well versed in the motions/controls enough to leave for more busy and faster roads! Like you say, it's all muscle memory, and once you have it it's very easy to forget how long it took to obtain the skills that you use in controlling the bike. Glad you've got back into it and are enjoying it again, ride free and stay safe.

[@RhinoDan]

William Guy Thilgen Jr. I don't think it was just the muscle memory also you haven't been on a bike for 20 years and speed on a motorcycle is totally different than a car. On a motorcycle we have so many more sensory overloads than driving a car which causes fear too. So I can see how riding home from the dealership would cause trouble if you haven't experience motorcycle speed in 20 years.

[@InsanityHere]

Please, you must tell the little lady that she needs to get her own motorcycle. Tell her you can still be friends, but that you think it's important for her to learn riding skills, indepentently. Tell her how much fun you have riding. Then, tell her of the inherent dangers of riding double. Please don't ride double. If the little lady wants to ride, please tell her to get her own bike. It's imperative you do so. I've been driving for many years. Please, don't crash while doubling.

[@Plague_Doc22]

[@parkerheathiii4881]

What a terrific illustration of what counter steering is all about. All good from where I sit...except for the assertion at 1:03 that angular momentum "is what keeps a rolling bike upright". I would argue that trail, built into the front wheel/steering geometry, is what keeps a bike upright at any speed. Simply put, trail geometry self corrects steering angle to keep a bike balanced (keeps the wheels under the center of gravity) whether turning, or going in a straight line. Gyroscopic effect, which increases with speed, resists any change in axis (and thus change in direction) of a spinning wheel. Gyroscopic effect is why changes in lean angle occur far more slowly at high speed than they do when initiating slow speed corners.

[@neilsbaker9790]

Brilliant video, I have listened to many attempted explanations but this is the first one that has explained the science in simple to understand logic.

[@acinonyx6333]

Gyroscopic precession is what you actually feel when you press on the bars. It's why there is such an instantaneous and direct response, regardless of suspension, tyre bend, pressure and any other 'soft' components; the torque on the bars acts on the wheel/gyro hub without going through soft connections It's also why you can slide both wheels and still maintain a bank angle without immediately crashing. Centripetal force turns the bike but gyroscopic precession steers it, if that makes sense

[@XtreeM_FaiL]

Justin Esdaile What do you think what would happen when you change wheel to a ski? How much gyro effect you feel after that? The bike still turn like before.

[@carlos1308]

[@inox1ck]

Looks like a very effective technique for quick turning I don't remember trying it before. The explanation is easy to follow. I can imagine now doing this and understanding each step what happens to the bike. So basically it allows you to lean fast, but you need to make sure you have enough grip at the wheels.

[@NoWayBiker]

CambridgeScienceCtr At 1:04, the narrator says that the gyroscopic effect keeps the bike upright. This is incorrect. The steering dynamics of the bike keeps it upright. When the bike falls over, the steering dynamics makes the front wheel turn in the direction of the lean, keeping the contact patch of the tires under the bikes center of gravity. The gyroscopic effect does help with keeping the bike stable, but a bike would never be rideable if you removed the steering dynamics. The whole consept of self balancing "safety bikes", which modern bicycles first was called, is the angled front fork which turns the wheel in the direction of the lean. Read this research about it: www.phys.lsu.edu/faculty/gonzalez/Teaching/Phys7221/vol59no9p51_56.pdf You should correct this in an annotation or in the description.

02:28 So basically a weight shift? Kinda like the car technique for getting into a drift/slide called the scandinavian flick, turn one direction and then aggressively turn to the other to shift the weight of the car to make it lose grip/traction. Except with motorcycles it's not an aggressive move, because unlike cars, motorcycles have that natural force behavior due to being on 2 wheels. Great video, really well explained. I understood everything I was meant to, I just wrote this comment because this counter-steering technique reminded me of the drifting technique. :)

Bravo! Outstanding presentation giving way to a crystal clear explanation of the physics. I had about 80-90% of the ideas in mind - including the "counter-steer causing the friction-torque to roll the bike in the direction you want to turn" - however watching a host of other KZbin videos took a toll on my intuition. Using the two circles to explain counter-steering should really be the standard. What I didn't quite articulate to myself was that changing the angular momentum of the tires *is the compensatory torque* to balance any differences between the other two torques, when changing the lean-angle. Amazing.

Holy love of clarity! So thought experiment- if you had a weight on a pole that is perpendicular to the bike vertical axis and extended towards the center of a curve, would that allow a bike to corner without lean? One last favor - can you touch GP riders position as it relates to cornering. Body position effects on “hanging off “ the bike meaning closer to center of the curve and any effects getting their body CG lower towards the ground.

1:06 "this is what keeps a moving bike upright" , no it's because when a bike starts to lean, the front wheel starts to steer into the turn, thus righting the bike. Check out Delft uni research.

[@tigerseye73]

Think about this; When you first learn to walk as a toddler, you learn how to balance yourself on two legs standing upright. Cool. Then when you are about 4 years old, Dad comes along and puts you on a small 2 wheel bicycle and gives you a gentle shove forward. The damn machine doesn't want to cooperate. After crashing 10 or 20 times, your young brain finally puts the problem into perspective and you begin to shift your body weight and handlebar in the proper direction to remain upright ( more or less ). Voila! You can ride a 2 wheeler without those pesky training wheels.Its somewhat counter intuitive to our sense of balance, which is why we have some trouble mastering it, but It stays with you the rest of your life.

Just watched a great video from some guys at Cornell. Couldn't find it on youtube. They determined that you can remove gyroscopic effect with counter rotating wheels above rolling wheels and the bike still turns into a lean... This is REALLY some heavy physics, but practically the only thing needed is for the bike to have a tendency to turn into a fall, and turn in MORE the greater the lean angle. Yes the leaning IS required as this vid states AND the gyroscopic effect does help because it does contribute to the turning into a fall behavior.

FINALLYLYYYYYY!!! NOW I UNDERSTAND HOW IT ACTUALLY WORKS!!

[@cesartejeida506]

Excellent and very didactic explanation, the laws of physics are unbreakable, but, what is broken is the bones.

[@Hyuts]

Beautiful video VERY well put together.

[@Bongo_Fury]

Best video to explain why counter steering works.

[@SwapnilGawari]

A very easy explanation...much appreciated

[@SahilSharma-xh9jv]

Just hit a pothole bigger than the one shown in the video. Thank you for the explanation. Will practice counter steering more effectively

[@karl4563]

Been using an MTB and fatbike for a couple of years and learned that u can make a turn almost without steering the handles by leaning with proper speed(u may fall if u are too slow) like the 1st explanation but never comes to my mind about counter steering just thought of it before like leaning on 1 side to make a turn and it feels really cool though andeasier to do on fatbikes. One thing is for sure, riding will teach u more about counter steering. Sorry for my English not my native.

[@EliminatorPerformance]

Poor guy during my motorcycle exam took this the wrong way and thought he better turn left to go right while going slow lol He dumped the bike and they failed him on the spot.

[@0991ekul]

wow i've been told how that all works but your video finally made it clear for me. thankyou.

[@motorelax]

Perfect explanation! Thanks!

[@bradster1708]

Good video but I was hoping you would make some mention of gyroscopic precession being the reason why the front wheel tilts when you push on the handlebar.

[@ridewithgnr2116]

This video explains several of the factors of physics regarding what is happening in a turn on a motorcycle. What is missing is the physics of pushing the bar the direction you want to go. How does that pressure affect the Motorcycle to force it to lean in the proper direction. Action/reaction from hand force forward on the bars intrigues me as Keith Code demonstrates for a moment in time the bars turn the “wrong” way and then “counter-steer” to turn, dive into, or lean the proper direction kicks in. “Splain it to me, Lucy!”

[@themoke3396]

Thank you so much for real content. thanks for your time and effort.

[@AlexanderSeling]

From what I read, it is centrifugal force that makes the bike lean outward against the turn and it is centripetal force that keeps it from "flying out" of the turn. Not sure which expert is correct.

[@Lehmann108]

Best explanation of counter-steer.

[@patthewoodboy]

also when you push right on a gyroscope (a wheel) it falls to the left. Try it by spinning a bike wheel held in your hand and push your left hand forward and right hand back to mimic a right turn , observe what the wheel does

[@wades623]

just think of it like this, the outside of the tire is what does the work in a turn. so if you want to turn right you have to get the right side of the tire to touch the pavement which means making the wheel go to the left that then makes more of the right side tire useable for the turn

[@johnnybravo4089]

wades623 thanks

[@japhle]

this finally shows what countersteering actually is, but I find it odd that this is something that I've always done so naturally on my bicycle to avoid pebbles/potholes/big cracks. that's what I would recommend to learn or practice it on, a new rider would be able to do it on your bicycle at 20 mph without worry of dumping their motorcycle..

[@BuzntFrog]

great video! How many times did you roll that little wheel until you got the proper curvature? Lol

[@JohnPatrick58]

I agree with all the others that say this is the first time they actually understand how it works now and so simply explained, the watch word here must be "ask an expert"!

[@themadman300113]

On the first point, you said if you don't lean enough you'll rotate out and fall, but if you lean too much presumably gravity will overcome the turning effect in the opposite direction, so you'll fall over / lowside your bike? It's surely not possible to have the turning effect completely balanced?

[@IAMDIMITRI]

This is like something you do since you where like 4 years old and learned to bicycle. Then you are doing the same when you are riding your motorbike. Then somebody sais that you need to know how to counter steer. WHAT NOW? I have do what now? Coutersteering is counter intuitive if you have always been steering by counter steering. Good video explaining how it works. Now I can explain it to people who never tried a motorbike before.

[@user-cx2bk6pm2f]

THIS is the power of intelligence. Well done!

[@ridewithgnr2116]

When riding a bicycle or motorcycle at a slow pace, “turning” out the handlebars/wheel results in the vehicle moving in the direction you point the front tire. When turning a Motorcycle through tight cures and at a rapid rate of speed, the front tire does not hardly change direction at all, as fairing mounted cameras will attest to. All of your explanations I believe are correct. What I am most curious of, is the relationship physics of force action/reaction plays once your hand pushes on the bar the same side as you wish the direction of the Motorcycle to go in.

[@lostinthecarolinas]

Great! Now can you show people why the front tire points INTO the turn once the desired lean angle is achieved?
