Can a Flat-Tread Motorcycle Turn? How Motorbikes Steer

[@thepaperboy9009]

I appreciate the massive effort of fitting "wheel barrow" wheels on a motorcycle, losing brakes and chain drive to prove a point. Well done. 🙏

[@jamesrindley6215]

You can get a similar demo if you're too cheap to change your front tire and it gets triangle-shaped. Handling will suddenly change in an unsettling way once the bike rolls onto the un-round part of the tire. It feels like you're sliding and gonna crash, but you can sort of get used to it. I don't recommend it though.

[@NONO-hz4vo]

@@jamesrindley6215 My friend had a bike that he had driving back several thousand miles on the freeway back from where he used to live and warned me the old tires were a bit square. It was a so unlike riding motorcycle and a huge understatement. I also don't recommend it.

Yeah, I don’t think you get it. He should’ve also said that when you iniciate the turn with counter steer and enter the corner you MUST let the steering go it’s way. If you still countersteer mid corner you will loose the front

[@FilosophicalPharmer]

Countersteering causes front tire to “track out”, causing the CG of the bike to become out of alignment with the plane of the motorcycle or bicycle. But because you are at speed, the leaning is offset by centrifugal force. In essence, turning a bike or motorcycle is a controlled fall without actually falling. 👍🏼

This is how motorcycle steering actually works, step by step: 1) Counter steering makes the bike lean over. 2) THE FRONT WHEEL IS THEN POINTED INTO THE TURN. THIS IS WHAT MAKES THE BIKE ACTUALLY FOLLOW A CURVED PATH. 3) Leaning keeps the bike stable when it is turning, otherwise it would fall over towards the outside of the turn.

@@banaana1234 That's kinda what I was thinking as well. If you're not used to using the front brake, and you get into a situation where you have to emergency brake... you'll probably just grab a fistful of brake and instantly trigger your ABS, which increases your brake distance. And if your bike doesn't have ABS your front wheel will lock and slide. That's because you don't have the muscle memory of how to brake correctly. Even when you have to brake as hard as possible, instantly applying full brake power is not correct, you have to apply less force at first and then quickly increase.

[@user-ju7dx8mu6d]

I had to add a few more comments. The tire (or as I like to call them truncated variable slant bicone)/ cone discussion is great and once you start to think of tires this way you begin to understand the intricacies of tire design. However, the discussion of counter steer is still weak. To truly understand the countersteer/lean duality, hold a rapidly spinning bicycle wheel with one side of the axle in each hand. Try to turn the wheel about the Y axis as if making a slow turn to the right. It will lean so hard to the left that it could rip out of your hands if it is spinning fast enough. Now try to lean the wheel to the left. It will turn to the right duplicating the motion you made previously. The lean and the twist are powerfully linked by the gyroscopic effect. When you try to accelerate the wheel around the Y axis you are acting against the huge momentum of the spinning wheel which creates a large slanting force. If you try to lean the wheel while preventing the twist, you will have a very hard time indeed. That is why you can turn a bike by leaning if you are riding no hands. When we turn by leaning we either instinctively do not prevent the twist or do not have the means to (hands free). We counter steer in unison with the lean because we have to. If you try to lean steer while tighly holding the handle bars, your grip is fighting your lean. So does it make a difference if you think you are initiating a turn by leaning or counter steering? I say it does. To shift your center of gravity is a big and slow motion which requires you to shift your body weight. Counter steering is short and fast and it uses the rotational momentum of the front wheel to lean both you and the bike with great force. For every day steering the difference is not important but for many rapid changes in direction and/or high acceleration turns, countersteering is faster, more easily controlled and ultimately less tiring because it generally takes less energy to apply a turn initiating force in your arms than it does to shift your weight. Love to see a video with you turning a spinning bicycle wheel in your hands.

At last, a correct explanation of the science of motorcycle steering. I've had countless debates and arguments with mainly US bikers about counter steering. Most refuse to accept that you can't steer a bike without counter steering. Here, in most European countries, counter steering is explained and practiced in preparation for driving tests. You have to prove during the test that you know how to counter steer to do an emergency sharp turn at speed. BTW, in Finland I have often seen bikers with normal car tyres mounted on their rear wheels. I've asked how this solution fairs and was told it needs getting used to, but after that is no different to a standard motorcycle tyre.

When actually riding the bike this is always the case! Never do anything else than coutnersteer. Sweden has a somewhat strange, but good anyway, part in the technical step of the final driving test for motorcycle licenses. It's called "lågfartsbana", a walking pace (chance of failure increases if you surpas ~7km/h) slalom with rather tight tolerances (hit the steer stops in almost every turn on my Street Triple) and 2 stops. The trick is of course to keep the bike upright as not enough centrifugal force is generated at that speed, and try to counter every degree of lean with your body. That course doesn't focus on countersteering.

[@FlyingAxel1010]

The steering is also noticeably different on a brand new pair of tires versus worn ones, presumably because of the difference in cone shape. I had to double check that my mechanic had installed the correct ones last summer. I was buying the same thing, but they felt so different from the old set !

[@0Rookie0]

We bought my SOs bike with a flat middle rear tire. I mean literally 3-4 inches wide of nearly flat tire. They only rode it on the highway so I guess it just never saw any action. It was odd having the bike "lift" up on lean initiation. Once we got the new one on, it felt like somebody took the training wheels off haha. Before, you almost had to force it on the side of the tire.

Yes. Which is why putting weight on the inside handlebar of a turn WILL actually make the bike turn. It's pushing the steering not offsetting weight from the center. Unfortunately Ryan equated that with "weighting the bike" and said it wouldn't make it turn. He also left off the part about the geometry of the steering and forks being the thing that is always trying to right the bike (it's not just rotational inertial, you can see this effect in a riderless bicycle going walking pace) which is why a constant pressure is required. Ease that pressure off the inside handlebar mid corner and the bike will want to stand back up.

Yes, Counter-Steering sets up the lean, but then the turn involves old-fashioned Car-Steering. Look carefully at videos of motorcycles coming straight at the camera and then turning, and you'll see the 2 actions. This 2-step steering occurs with all bodies with the center-of-mass above the control surface - bicycles, 2-track roller skates, ice skates, skate boards, surfboards, water skies, snow skies - there is 1st a control surface input to cause a *ounter-turn* , then a "regular" control surface input to turn *toward* the intended direction. For paragliders, where the control surface is *above* the CofG, the turn proceeds in 1-step.

[@NotKalashnikov]

Yes, counter steering is used to lean the bike over. Further steering is used to balance between gravity pulling the bike to fall toward the turn and centrifugal force trying to stand it up. I think he is fundamentally wrong with his last point.

[@ChristopherKerns-n6r]

Yes ! finally somebody said it ! The front wheel goes where the handlbar tells it.

[@daemn42]

FWIW, all balancing modes of transport use countersteering to initiate a turn. Skiing, snowboarding, running, etc require that you outtrack to initiate a quick turn. Anyone who's ever been running and got trapped on the edge of the sidewalk or a curb unable to turn away without putting their foot in the grass or on the street will understand this one. We even do it at walking speed, but it's less obvious because our feet are naturally a little bit to one side or the other of our CG, so an outtrack to the right just means putting your right foot down not exactly under your CG, causing you to lean to the left slightly to start a left turn. For skiing and snowboarding it's a little tricky to outtrack while going perfectly straight, which is why we tend to carve out large continuous turns with the skis or board just flat enough to cause a little bit of side slip. If we're in a large radius left turn, we initiate an outtrack further to the left, by setting the edge to decrease the turn radius. The board or skis go left quicker (an outtrack to the left in a slow left turn) causing our CG to cross over to the right side, and initiating a right lean, and thus the right turn. Understanding that all turning requires counter steering, really helped me learn how to ride a snowboard.

[@kenthartfield3237]

You have exceeded your knowledge by a fair amount. Single track vehicles countersteer. Skiing and walking/running are not that.

[@daemn42]

​@@kenthartfield3237 You're entitled to your opinion but the physics is clear, and entirely testable. They're both still balancing activities. Try this easy one yourself. Establish a brisk walk right on the right edge of a sidewalk (for safety find some place with grass at same level on both sides) and then at some point try to initiate a quick 90 degree turn to the left. You may be able to make a slow turn by just shifting your upper body weight over the course of a couple steps (much like riding a bicycle without hands), but if you want to change directions quickly you'll find that you have to step off the right edge of the sidewalk (outtrack/countersteer) to do so. Now try going straight, then zig zag at fast walk, then jog, then running pace. Notice that subconsciously (until now) you always wait until you can plant your right foot wide to initiate a hard left, and vise versa. As for skiing. If you're going down the hill in a wide stance you may not think you're countsteering because your weight is on both skis, but consider that to initiate a left turn you have to put more weight on the right ski. You're shifting your contact point to the right below your CG, to turn left, and vise versa. But what I was talking about is the way people ski when they go fast on packed/goomed snow, feet mostly together carving big turns. If I'm carving a left turn and need to switch quickly to the right, I can either force my left foot out further left and put my weight there (still outtracking as above) *or* I can roll up onto my skis left edges which (due to their shape and our rearward position on the ski) causes the skis to turn more sharply to the left which throws my body over the skis to the right. Visually we may perceive it as the skis cutting left and right while body just goes down the fall line, but you can't make that transition quickly without countersteering. To be clear, I do ski, and I transition this way. What I do looks no differently to how anyone else skis, I just am aware of *how* I'm doing it, just like someone who knew how to ride a bike and now consciously countersteers.

[@kenthartfield3237]

You are just spouting nonsense. Nothing you described is countersteering. Both skiing and walking are analogous to a double tracked vehicle which does not countersteer to initiate a turn. It may be that you like to turn in the wrong direction before you turn in the right direction while walking or skiing but it is neither required nor helpful to making a turn. Have you wondered why no book or video on skiing has ever mentioned countersteering? Have you ever wondered why no book or youtube video has ever discussed countersteering in the act of walking? It's because it doesn't apply. So tell me, Is ignorance actually bliss? Inquiring minds want to know.@@daemn42

@@kenthartfield3237 My assertion is testable and falsifiable but you didn't bother to take the 5 minutes to step outside and test it yourself. Just because people don't realize they're doing something doesn't mean it's not still happening. The idea of "countersteering" didn't exist for about a century yet people were still doing it while riding bicycles first and then motorcycles every day. Then people would assert "it only applies at high speeds" and that myth persisted for almost another half century, but is easily disproven. As for "multi track vehicles" the wiki article for countersteering points out "Free-leaning multi-track vehicles must be balanced by countersteering before turning." For skiing to not be free leaning you would have to maintain a fixed super wide stance where you don't lean your body, especially leaning inside your inside ski. And walking is 100% a balancing activity. There's no way to walk while keeping both feet in contact with the ground all the time.

I just love the use of science and physics with a fun style to explain and teach motorcycle riding.

[@bikersquest]

This cone explanation is also why new tyres feel like they tip into corners a lot easier than old squared off tyres.

[@jdrosner1]

If that's the way your tires wear. Mine get more cone shaped towards end of life especially the front. It gives the opposite effect.

[@K0nst4nt1n96]

I watched twist of the wrist 2 and its still the best thing to do as a newbie.

[@TheEmptyHoliness]

Hi Ryan! I love your brilliant mind and presentation style. I don’t have much…any…interest in motorcycles generally, but I really love watching you as a host and I really love when you talk about the science as well as the way you present it. (The goretex video was supreme!!) And I wanted to say that I would really love if you branched out more. I feel like the top gear style of presentation you have perfected and improved upon is so well suited for a more diverse range of topics than just motor vehicles. So here’s hoping that the future will include many videos that have little or absolutely nothing to do with motorcycles. Maybe even just a second channel about products, science, and the ways in which capitalism fools us all into buying things that are not all they claim to be.

[@karlbishop7481]

This the best explantion of how a motorcycle turns I have heard or read in my 60 years of riding. Reinforces why I need to get new tires for my V7. I have used Cobras and Cobra Chromes for years and find they corner very well. I have heard that Avons are no longer made since Goodyear acquired the company. If true, sad and I don't know which way I will go.

[@albarytu]

While it's true Goodyear acquired Avon and have closed the UK-based factory, I think they were planning to produce the Cobras and some other models somewhere else in cheaper-to-run factories. They announced "the Avon brand will remain a key part of Goodyear’s portfolio" less than a year ago. At least I hope that holds true because I ride a Rocket 3 and there are not many alternatives.

[@karlbishop7481]

@@albarytu I heard that too and then I heard later that they were quiting the Avons completely. I really can't vouch for the authenticity of that statement at all. I hope that is incorrect.

[@CplVasilli]

Lol. As soon as anesh comes back the video quality skyrockets

[@nevarran]

The counter steering is so instinctive that most people don't realize they are doing it. And not just causal riders either. I remember watching an interview with Valentino Rossi and as he was saying that on a left corner he pushes forward with his left hand he paused and was like "hmm... yeah, left forward".

[@zoegagnon3651]

This is the first time I've heard cone shape as a major contributor to steering. Also very interesting that the trailing rake of the front axle wasn't mentioned at all. I think there may be more at play here and would love some references to follow up on

[@HALLish-jl5mo]

He's covered caster angle and caster displacement on his Rune video. Minute Physics's video on why bicycles self balance is probably the best overall video. That really taught me that the art of riding is off balancing the bike in a controlled way, and letting its dynamics do all the work to actually steer. At least over about 10 mph.

[@scenicdriveways6708]

Love that little Susuki RV125, wish it were mine. :(

[@FreekToTakex]

That Mutant is an absolute miracle. Turned my run of the mill commuter NC750X into something you can actually have a lot of fun with! Also, not unimportant when riding year-round in rainy Dutch weather, it’s great in the wet!

[@ytashu33]

As a physics buff and a motorcycle buff, this was pure candy! I am too cheap to take Keith Code's riding school, but i do have his "A twist of the wrist", worth every penny!! Awesome to hear his name being mentioned by my favorite moto vlogger!

[@wadeblake3451]

If you happen to live in southern BC, Keith’s school is only a 90 minute ferry ride and 2 1/2 drive away. Just saying.

[@ytashu33]

@@wadeblake3451 I am in California, so the "original" school is not too far either. It is not the distance, it is the time/money investment part... Some day... BTW, was in BC/Yukon area recently to checkout the Northern lights, breathtaking beautiful place you guys have got up there!

[@Grim_Beard]

Counter-steering initiates turns, but _in_ the turn you 'normal' steer - as shown repeatedly in this video. That may be where some people's confusion arises, not distinguishing 'turning' (i.e. the whole process of changing direction) from 'initiating a turn'.

[@PendragonDaGreat]

I don't have a motorcycle, not even a license endorsement (though I plan to in the not too distant future), but I've been riding my road bicycle in excess of 25 mph for years and years. Everything you say here applies there as well. Excellent application of the physics.

[@roadrash999]

@3:30 that seemed dangerous dude, one accident and you're under a car.

[@FortNine]

Yeah it was, wouldn't recommend. ~RF9

[@martinburns342]

Hi Ryan. Great video. I attended Level 1 of California Superbike school at Eastern Creek Raceway in Sydney about 15 yrs ago after writing off a Honda CBR600. Improved my riding greatly. Keep up the great work. 🇭🇲

[@braziliansheetbox2497]

Fun fact: when i drive my bicycle with no hands i still do counter steer

[@brucehatcher4091]

As an instructor, I can confirm just how misunderstood this topic is, even amongst 'experienced' riders. Great video. Motorcycle turning myths busted!

[@tubixtz]

right. except part tree is mostly nonsensical.

[@electricsynthesis]

Still no reply to driving4answers on the 270° crank?

[@jiglesmackle4081]

i recently started watching your videos and i dont even ride motorcycles. So beutifully made videos. Captivating, educational, funny. Very quickly becoming one of my favourite channels

[@rightwingsafetysquad9872]

The problem with the "normal steer" portion of the video is that he's going way too fast for the normal steer domain. It's only applicable when you're going slow enough to be putting feet down. Everything Ryan says is true, it's just not applicable unless his intended audience has never ridden a bike before.

[@domfer2540]

Many decades ago on my Silverwing I was a part of MCF training program, on counter steering. Our training ended up as part of MCF program.

[@robertconklin3322]

A fantastically informative video. The Jazz injection is pure production genius. I watch your videos as much for the delightful and engaging production work as I do for enthusiasm on the topics. Thanks effnyne

I only have limited mobile data to browse the web, but fortnine videos i stream in the highest resolution. I never regret it. Thank you RyanF9

[@andrewhall836]

Too many ... "Oh ... Yeah!" and "Oh Sh*t! Of course" moments to comment on. Ryan manages to tell you what you know instinctively in ways you can understand!!! And all with a sense of Humour!! Brilliant!!

[@Dodge94CTD]

I constantly say watching your videos has made me a more informed rider. Thank you.

[@_Makanko_]

I was already planning to go to the Mutant for my next tire set, nice to see some extra approval.

[@chrispewkreme]

For people that don’t ride or have a way to feel this, grab a broom. Balance the tip on your hand. And get you and the broom to a walking pace. You’ll quickly learn you have to move the broom backwards, then let it rip over, and then you can move forward as it tries to fall and impart enough force to keep it up.

[@CannyDanny]

I still remember doing my CBT at 16 years old, many moons ago, and the instructor saying if you want or need to turn fast, flick the steering in the opposite direction. The harder you do it the quicker you'll turn the other way. I remember being quite doubtful at the time, but all these years later I have used this a number of times to quickly evade an impending accident.

[@ratmphan]

Man, I love this show. Also, because of the same principle as counter-steering, you should always face the handlebars at full left lock when parking a bike with a left--side mounted kickstand.

[@KimmoJaskari]

Been running the Avon Cobra on my Rocket 3 for years now. Absolutely fantastic tire. Wouldn't want anything else.

[@Hurtydwarf]

I saw a video sometime last year of lots of leaning/counter-steering/physics stuff revolving regular bicycles and I'd say a lot of what they discussed applies here. He made a bike that they can remotely lock you out of a steering direction. Every single person fell without the ability to steer the bike one way or another. The bike also couldnt keep itself upright when ghost rode without the ability to steer. There are a lot of forces that go into bikes/motorcycles staying upright.

[@carryonpompei]

That was a Veritasium video.

[@jamessmith9786]

One of the all time BEST, and you all have set a very high bar!

[@tstephen951]

Nicely produced video. You have skills most KZbinrs would dream of having. Your delivery, choice of music and cadence are spot on...

[@SingleBladedRonin]

One thing I learned when I took my motorcycle permit class: to avoid and obstacles you can either break hard or push the bar in the direction you need to go.

[@nazeem3296]

I used to believe in myth #2. None of the other physics gurus in youtube could explain/demo it clearly. Well done !!
